Does anyone know?

...where the fire shoots out from on Mario in Mario Brothers? Was just playing the first one fried & was wondering if the fire came from his mouth, hand, belt...? It's hard to tell really & I've never thought about it, aha.

@ 0:05 & 0:15 you can see him shoot one.

His hand he throws it ,he must pull the fire from his A hole? Spicy
