John and Jennifer Seal are two anthropomorphic seals who live in the 'Pearls' neighborhood.
John is stern and smart, as he is the one The Killer Whale always confronts. He wants to protect his wife from certain death.
Jennifer who likes John, and used to be somewhat scared of The Killer Whale, but at some points she scolds John for being rude to it.
Pig seems to like John, as in the party, he felt a little concerned about why John didn't like his seating arrangements.
Rat seems to not really care about them, as he attempted to kill them by seating them with the Killer Whale.
