Bubble

Bubbles are animated furniture blocks bought from the Party Girl after the world is in Hardmode. When these blocks are placed together in groups, they connect to make a seemingly single larger bubble block. They can also keep liquids in them, but the player doesn't collide with the block itself. This makes them perfect for honey buff pickups for arenas, lava traps for flying enemies and water pickups for the "wet" buff when mounting Cute Fishron.

Mechanics
Bubble block is a very special block. To players, NPCs and items, it is taken as air; to liquids and other tiles, it is taken as solid blocks. So you can use perma-solid blocks and bubble blocks together to contain liquids.
