Qwilfish (Secret Wonders 101/132)

Abilities

Once during your opponent's turn, if Qwilfish is your Active Pokémon and is damage by an attack (even if Qwilfish is Knocked Out), you may flip a coin. If heads, the Attacking Pokémon is now Poisoned. Put 2 damage counters instead of 1 on that Pokémon between turns.

Attacks

It shoots the poison spines on its body in all directions. Its round form makes it a poor swimmer.
