And let her taste the fires of hell!!
I was going to point out about Poochyena being a Dark type (thus immune to most psychic powers), but then I remembered that in PMD it would be "ineffective" (0.5x) instead. Though Houndoom was immune to a psychic attack back when facing Grumpig instead of taking minimal damage, maybe here there's a difference in interaction when it comes to attacks.
Speaking of immunities, I'm guessing that Flash Fire isn't going to work on this kind of fire?
