The Cast

A bright-blue plasticine humanoid with googly ping-pong eyes and strand hair. Relentlessly game — he treats every reality-shattering catastrophe like a minor errand. Despite the name, there is no giggle.

A tall, lanky, deadpan tuxedo cat with droopy half-lidded eyes and a small red bow tie. Profoundly loyal, a half-step behind, and cursed to mutter “…That reminds me of my tooth.” every single episode.

The too-perfect dad next door. Always “Mr. Jefferson,” never a first name. Smug, petty, and usually the one who detonates the whole episode.

The too-perfect mom next door, famous for her block-party bread. Always “Mrs. Jefferson,” never a first name.

Unsettlingly perfect and doll-like. Speaks only in sweet-voiced ominous prophecies that always come true by the end of the episode.

The sweetest, most normal kid imaginable. Nobody — not even strangers, not even the narrator — ever calls him just “Mark.” It's always something unprintable first. No one ever explains why.

A calm, perpetually slightly-damp man in a wetsuit who is already there in every world the boys teleport to, working a different absurd job each time. He never acknowledges the pattern.
