Jumping Bubble

The Jumping bubble is a simple enemy that cannot be killed in any way, except when using the Water Gun. This strange comparison makes people believe it is related to fire in some way, or simply a sentient ball of magma.

Strategy
Since this enemy is unkillable, and will kill the player in one hit no matter what sort of armor they have on, it's best just to avoid them completely. It is recommended that the player always has a water gun in their inventory, just in case.

Drops
This is one of the very few enemies that has no drops, and mostly just act as obstacles.

Trivia

 * It is highly believed that this enemy is inspired from the Lava Bubble, an enemy from the Mario series.
