This ability can be granted by inhaling either Flamer or Fire Lion.

Burning is provided by either Flamer (in single-player mode) or Transformer (in multiplayer mode, albeit Transformer also provides other abilities in the game).

In this game, Burning can be granted from Flamer (once again), Efreeti (after defeating it), or from Mr. Bright's stars.
