Items

Bubble Net

Used to catch bubbles for helpful effects when consumed.

Water Bubble: 5 Oxygen

Lava Bubble: 5s Fire Resistance

Bubble Wand

A useful item for transportation. The longer you hold right-click the bigger, the bubble grows, giving it a longer lifespan. The bubbles can be ridden upwards. 

Golden Bubble Wand

Crafted from combining a Bubble Wand with The Heart of the Sea. Spawns a bubble companion that helps you with storage. Its size grows the more items you store inside it.

Throwable Bomb

Can only obtained by catching Bomb Bubbles. When thrown, it has a short fuse and explodes similarly to TNT.

Features

Want to make your bubble pet unique? Change its texture by adding a tag to it. For example, the Lava tag will change your companions texture to a Lava Bubble.
All tags: Lava; Water; Gold.

Be careful when trying to pop a bubble near bombs. Bubbles usually pop in chains, so this could trigger a chain reaction. 

Remember that the bigger the bubble, the more loot it contains.
