For Character pompano, see Peter.
Strangelly, pink pomapnoes are bigger than Harry. Though, when first to play as Harry it will say he's bigger than Peter, which is a pompano.
In Goliath levels, pink pompanos are one of the smallest fish he can eat. Others are also tuna, but in Harry levels tuna is big and pink pompanoes are medium. In Goliath levels, they are the same size.
