What it is: Sparkling Skylands is the final floating base-story region. The central job is helping Tinkamaster rebuild the Huge Building (Concrete, lifts/Tinkagears, floors) — not a weather-boss farm and not a Rayquaza request.

Unlock (live-accurate): Start in Withered Wastelands. After Important Request “Yawn up a storm!”, Bleak Beach and Rocky Ridges open as a branch (either order). Clear both Beach and Ridges story lines before Skylands opens. There is no documented 40% restoration unlock and no invented hour gate (e.g. 280h).

First beats after entry: Explore scrap islands → meet Tinkamaster → unlock Concrete (Conkeldurr mixer) → get Tinkagears / repair lifts → stockpile for 2F–4F → finish floors → rooftop Master Ball scene reveals Mewtwo.

Sparkling Skylands Huge Building and Mewtwo walkthrough

Sparkling Skylands is the enormous floating region built over what used to be Celadon City and Saffron City. The catastrophe sent the ground into the sky, and the region’s central job is not a weather hunt or a secret boss: it is rebuilding the remains of Silph Co. into a Huge Building that can welcome humans and Pokémon again.

This route was checked on 2026-08-26 against Serebii’s current Sparkling Skylands location record, Important Requests walkthrough, crafting list, and legendary record. It replaces an older version that assigned unsupported locations, resources, spawn counts, and a different legendary to this area.

The short route

  1. Explore the scrap-filled islands until you meet Tinkamaster, the special Tinkaton interested in human machines.
  2. Follow its request to make Concrete with Conkeldurr and the mixing machine.
  3. Receive Tinkagears, repair the area’s lift network, and establish safe travel between elevations.
  4. Stockpile the materials for 2F, 3F, and 4F before committing your helpers to the Huge Building.
  5. Finish all three floor projects and go to the roof when the new noise and portal appear.
  6. Watch the Master Ball open and reveal Mewtwo.

The floor requirements are sequential. Prepare early, but expect the project prompts to advance one floor at a time.

Step 1: meet Tinkamaster and unlock Concrete

Tinkamaster is curious about the human machinery scattered through Sparkling Skylands and believes the broken skyscraper can be restored. Its first practical obstacle is Concrete. The story points you to Conkeldurr, whose mixing machine opens that production route.

The crafting record lists the Concrete mixer at 2 Iron ingot. Once Concrete production is available, do not spend every batch on decoration: the Huge Building alone consumes 90 Concrete, and the lift network consumes more. Keep a dedicated project reserve.

Sparkling Skylands naturally supplies or exposes many of the materials this arc uses, including Iron ore, Pokémetal fragment, Rare Pokémetal fragment, Wastepaper, Small log, Lumber, Wheat, Bean, Leppa Berry, Stone, and Vine rope. The location also contains Skyland deposits for Copper, Iron, and Pokémetal. Mark productive nodes and revisit them while other project steps are active.

Step 2: repair movement with Tinkagears

After the early Concrete task, Tinkamaster gives you Tinkagears to help restore the lifts. The standard Lift platform recipe is:

IngredientAmount
Iron ingot5
Concrete5
Tinkagear1

Use lift platforms as infrastructure, not decoration. Connect the routes you repeatedly use for ore, the Huge Building, and resident housing. A shorter supply loop saves more time than a decorative platform placed on an island you rarely revisit. The crafting list also documents an Elevator platform later through Poliwrath’s request for 8 Glass, 8 Concrete, and 2 Tinkagear; that is a separate recipe, so do not confuse its costs with the basic lift.

Step 3: rebuild the Huge Building

The Important Request is called Rebuild the Huge Building. Each floor combines materials with an active Pokémon helper requirement.

StageMaterialsPokémon help
2F25 Concrete, 10 Glass, 5 Pokémetal, 10 Iron Ingots6 Pokémon, including Professor Tangrowth
3F25 Concrete, 10 Glass, 10 Glowing Stone, 15 Copper Ingots10 Pokémon; Chef Dente is recommended for the restaurant
4F40 Concrete, 15 Glass, 10 Paper, 10 Brick, 20 Lumber15 Pokémon; Peakychu is recommended as an outgoing helper

The helper counts are requirements for each construction stage. They are not evidence that the area contains 31 unique species, and the guide does not turn them into a regional spawn total.

Combined material checklist

If you want to gather the entire building budget before the final push, the arithmetic across 2F, 3F, and 4F is:

  • 90 Concrete
  • 35 Glass
  • 5 Pokémetal
  • 10 Iron Ingots
  • 10 Glowing Stone
  • 15 Copper Ingots
  • 10 Paper
  • 10 Brick
  • 20 Lumber

Paper only appears in the 4F bill, so Wastepaper that looks unimportant earlier becomes useful later. Keep Professor Tangrowth available for 2F. Recruit enough residents before 3F and 4F rather than arriving with materials but too few helpers. Chef Dente and Peakychu are named recommendations in the source route, making them sensible members of your active roster.

Step 4: the rooftop Mewtwo scene

After 4F is complete, the story calls attention to a noise on the roof and a portal-like event. Climb to the rooftop. A Master Ball appears and opens, revealing Mewtwo. Mewtwo is surprised because it feared humans had returned, then recognizes what you accomplished by rebuilding the skyscraper.

This is Mewtwo’s story appearance, not the same thing as securing a resident. The current legendary record documents Dragonite Doll as the Dream Island tuning item for Mewtwo. Tuning only favors that island result; it does not guarantee Mewtwo on the next trip. When the correct resident appears, speak to it and use the Dream Island bring-home flow. Our legendary Pokémon guide separates every story appearance from its recruitment method.

Useful Environment Level shop targets

The Sparkling Skylands PC shop expands as the local Environment Level rises. These are selected, source-listed milestones rather than a made-up progression formula:

LevelUseful unlocks
2Mailbox, Office chair, Asphalt road recipe, Concrete steps recipe
3Poké Mart kit, Office cabinet, CD player recipe
4Concrete slab recipe, Metallic smelting furnace recipe, Window pane recipe
5Game Boy system, Yellow hut kit, Glass window recipe, Simple door recipe
6Pokémetal, Mini generator recipe, Glass pane recipes
7Rare Pokémetal, Pop art table recipe, Rough wall recipe
8Small office kit, Pop art lamp recipe, Shop flooring recipe
9Gaming chair recipe, Gaming light recipe, Pokémon Center wall recipes
10Skyland Pokémon Center kit, Gaming fridge recipe, Gaming PC recipe

Treat these as rewards for improving the region, not prerequisites for the three Huge Building floors unless the active request explicitly says so.

Troubleshooting stalled progress

Tinkamaster is waiting for Concrete

Return to Conkeldurr’s mixing-machine route and confirm you are carrying the finished material, not only Stone or ore. Reserve enough Iron ingot for both the mixer and lift platforms.

A floor will not start

Read the active project panel again. Check materials and the Pokémon helper count separately. Having 25 Concrete for 2F is not enough if Professor Tangrowth or the six required helpers are unavailable.

A required story Pokémon disappeared

Serebii’s patch history records a fix for an issue where story-required Pokémon in Sparkling Skylands could disappear. If your software is behind and the request marker has no character, update the game before rebuilding unrelated structures.

You expected a fixed species total or a weather boss

The current location and Important Request records do not publish those rules. Use the Sparkling Skylands Pokémon guide for the source-backed distinction between story characters, habitat residents, and Mewtwo’s later recruitment state.

FAQ

What should I stockpile before starting the Huge Building?

Prioritize Concrete and Glass first, then preserve the smaller floor-specific bills: Pokémetal and Iron Ingots for 2F, Glowing Stone and Copper Ingots for 3F, and Paper, Brick, and Lumber for 4F.

Does completing the rooftop scene guarantee a Mewtwo resident?

No. The roof is Mewtwo’s story appearance. Dragonite Doll favors the separate Dream Island resident route, and the tuned island is not guaranteed on the next trip.

Is there a verified Rayquaza request in Sparkling Skylands?

No current request or roster source used here documents one. The verified final encounter in the Huge Building story is Mewtwo.

Sources and verification scope

The review records the published route as of 2026-08-26. Updates can add requests or residents, so a later patch should be verified against the live records rather than inferred from an old checklist.
