Collection space
The home aquarium displays progress and gives collected creatures a persistent place outside individual puzzles. Its contents can change as new species and events arrive.
Temporary level containers
A container offered during a difficult level may apply only to that run. Read the confirmation text before spending coins or watching an advertisement.
Decorations
Treat decorations as cosmetic unless the game explicitly describes a gameplay effect. Record unlock requirements separately from strategy advice.
Before spending currency
Check whether the purchase is permanent, event-limited, or single-use. This distinction should be visible in every future Wiki entry.
