Flaming heads
Oh boy, it’s like the Syphon Filter taser all over again.
If you want to give your Kirby a new look, try getting sucked off by another Kirby while you have your hammer readied and release your grip right when you start getting inhaled. The flames from Kirby’s mallet will then be affixed to his head until he uses the hammer again or dies.
If you’re real sneaky, you could probably use the flames to mask your moves.
