Sunken Plant Zone 3

Sunken Plant Zone 3 (MAPBC), is the sixth boss in Mystic Realm. Although the player can see where the slime has landed, unlike Midnight Freeze Zone 3, SPZ3 is much harder. Almost the whole floor is breakaway; the rest that's left is just thin edges and a cross to walk on. The stage is set entirely underwater, so the player must also focus on grabbing air bubbles on top of attacking Dr. Eggman.

Walkthrough
To explicitly show know where not to go, jump on the four breakaway quadrants of the stage, making sure you end up on solid ground. After that, refresh your air supply. Now go and attack Eggman. Every time you hit him (except after the seventh), refresh your air supply or you'll drown.
