Moves[]
Isaac is a Jigglytuff that early learned the move Dragonbreath. That's why it was given the name of Dragon Slayer. Therefore his relationship with Trapinch became more complicated, because of the latter destined to become a dragon. Fortunately the move was the first to be forgotten. Isaac's moves are by now Heart Swap, Growl, Spite and Hidden Power.
