Can Creeper

The Can Creeper is a two-phase mini-boss found in The Junkyard. In Phase 1 it hides inside a trash can shell with 40 HP that can only be damaged from the front — side and rear attacks have no effect. As it moves it leaves Creep on every tile it vacates, and its Slide movement ability launches it 6 tiles forward while spawning a Fly. Its ranged attack spits two diagonal projectiles simultaneously.

After taking 40 damage it sheds its can shell, entering Phase 2 with 20 fresh HP, speed 5, and vulnerability from all directions. In this phase it becomes immune to Electric damage and can only attack while standing in Creep, the slick residue it has been laying throughout the fight. Electric attacks conducted through Creep can bypass the Phase 1 directional restriction. Hunter traps do not affect this enemy.
