Summary
Using Inhale in Melee leaves the character's hurtbox while inside Kirby's mouth. It is invisible and intangible. However, since blast lines ignore invincibility, Bowser will be KO'd first. (the yellow line represents the blast lines and the blue box is where the character will hit the blast lines. Notice Kirby's box is much higher than Bowser's.
