What Makes this set WOW?

3-in-1 model: The set offers high replayability, allowing you to rebuild the aquarium into a realistic painting easel with a fish or a pirate treasure chest.

Five recognizable species of fish: The structure includes block-built models of a clownfish, a kingsnake, a barber, a mermaid and a cardinal, which have movable elements.

Transparent display frame: The use of light blue, transparent blocks imitates water, creating an aesthetic casing that looks great as an interior decoration.

Underwater micro-details: The interior of the tank is filled with colorful corals, sea plants and unique accessories such as a miniature crab and a small submarine.
