The Museum is a released Waterpark Simulator 1.0 progression location. CayPlay’s launch notes confirm three NPCs, three questlines, and one currency for each line. Those currencies unlock three research branches—Aztec, Sea, and Pirate—and every branch ends with a massive themed slide.
The official announcement does not name the NPCs, currencies, task sequence, costs, or rewards beyond that structure. This guide therefore gives a spoiler-light way to record and complete the live objectives instead of fabricating a walkthrough.
Find the live objective before planning
Enter the Museum through the current public build and speak to the available NPCs using the prompts shown in game. Record the exact quest text, its source NPC, the currency symbol or name, and the theme branch it appears to support.
Do not rename an unfamiliar currency from a search snippet. The 1.0 post establishes that there are three distinct currencies, so a correct note must preserve which questline awarded which one.
Choose one active objective that matches normal park work when possible. If the task asks for an action, complete the visible requirement and return through the current quest interface. Exact task order is intentionally not asserted here.
Keep a three-line quest ledger
For each NPC, maintain a short record: current objective, progress shown, reward shown, completed date, and next research node you want. This prevents currencies from being treated as interchangeable.
Update the record only after the live screen changes. An older 0.x guide can identify a possible question but cannot prove the current 1.0 value or sequence.
If two objectives overlap with ordinary operation, progress them without destabilizing the park. If a task would require expensive construction, confirm the reward and the chosen theme before committing cash.
Match currency to theme research
CayPlay confirms the branches as Aztec, Sea, and Pirate. Open the research interface and verify which of the three Museum currencies the selected node requires. Read prerequisites and costs from that current screen.
Spend toward a coherent district rather than unlocking one decorative item from every branch. A small complete themed area can be tested for access, guest use, cleaning, repairs, and service. Scattered unlocks may consume all three currencies without producing a usable result.
Reserve space before pursuing a branch’s massive slide. The official notes establish that each branch ends in one, but they do not give dimensions or construction costs. The final unlock is more useful when the park can fit and operate it.
Separate visual evidence from mechanical effects
Official previews describe Ocean pools with coral and marine styling, Aztec pools with carved-stone finishes, and Pirate pools with a high-seas character. Those descriptions establish the visual identity of the released themes.
They do not establish a hidden happiness bonus, capacity increase, safety modifier, or income multiplier. Treat a themed item as visual and construction content unless its live research card states a mechanical effect.
Capture any effect text with the public version and date before relying on it in a build plan.
Avoid losing progress to an uncertain spend
Before buying an expensive node, save through the normal game interface. For a valuable park, make a manual copy using CayPlay’s official save location described in the save recovery guide.
Check that the currency belongs to the intended branch and the unlock can be placed or used now. If the park lacks room, operating cash, or prerequisites, wait rather than converting a quest reward into an unusable unlock.
After purchase, build or inspect the unlocked item and note what changed. That gives the next decision actual evidence.
Museum problems and safe recovery
If an objective seems stuck, reread the exact current text and reproduce only that action on the public 1.0 branch. Check whether the game displays a difficulty, map, park state, or count requirement. Do not substitute an older task with similar wording.
If currency does not appear where expected, verify the quest was completed and claimed and that you are looking at the corresponding theme tree. Keep the three lines separate.
If the Museum is unavailable, confirm the current save’s progression and prerequisites in game. No unlock threshold is stated here because the official sources reviewed do not publish it.
If a quest still fails, record the objective, visible progress, save scope, difficulty, and current version, then use CayPlay’s Steam discussion or support route. Avoid editing the save.
Museum questions
How many Museum NPCs and questlines exist?
Three NPCs open three questlines in version 1.0, with one special currency attached to each line.
What do the currencies unlock?
They feed research for Aztec, Sea, and Pirate themes. Each branch ends in a massive slide.
What are the currency and NPC names?
They are not asserted because the developer’s release text does not publish them and this pilot has no live 1.0 capture. Use the current in-game labels.
Is the Mafia part of the Museum?
The official materials describe Mafia as a separate optional mini questline involving a loan. Do not merge it with the three Museum branches without live evidence.
Can I complete every branch?
The public materials establish all three branches but do not publish every prerequisite or cost. Follow the current tree and treat full completion as a live-version goal.
