I Was Bitten

S03E05 Lil' Porkchop

Billy declines his father's offer to go fishing and instead adopts a small, frail fish he names Little Porkchop. To lift Billy’s spirits, Grim magically transforms the fish into a massive creature overnight. Billy takes Porkchop outside to enjoy the sun, neglecting to provide any water. Tragically, the fish eventually turns to ashes and is flushed down the toilet. When Billy's dad comes back from his fishing adventure, he brings home a fish that resembles the now-normal-sized Porkchop, unaware that he intends to cook it.
