This is a simple "boss" that shoots projectiles at Mario and takes a customizable amount of hits. It's only damaged by collission with Marine Pop's projectile, so make sure you have a Marine Pop in your level.
You might want to use No More Sprite Tile Limits.

v1.5: Now can teleport around and lock the screen, as well as allow it to scroll again after being defeated.
This boss, while simple, have its charm, albeit, you could improve its code a bit and make it a bit clear, even though it does its job. However, this boss have some nitpicks that already have been described by LX5, nevertheless, it is a good job and I hope you can do more sprites.
Just a minor thing, it gives issues if you are using Sprite Tool with asar, I took the freedom to include a .cfg file that points to asar usage, should you ever use it.
