This is a customizable version of the Green Bubble sprite which is typically used in ghost houses.
New options include:
- Movement options like making it only go in a particular direction or go back'n'forth like a Flying ? Block.
- Homing version which goes towards the player constantly akin to the pink bubble from Casio Mario World.
- A bubble that tracks mario horizontally like a Disco Shell.
These attributes can be selected via the use of extra bytes. (which I explain in the ASM file, so be sure to check that)
Note: Also includes a disassembly of the green bubble which I did myself since the one already on the site was not user friendly and easy to customize.
