The Silly Sea Sponge announces himself with a laugh, a big, easy one that has the room grinning back before anyone's heard the joke. He's endlessly sure of himself, certain he could out-cook, out-dance, or out-bubble anyone in the yard, and he's right just often enough to keep trying. From his very first hello he treats the birthday child like a friend he's simply been away from for a while, not someone he's meeting for the first time.
Families all over Greater Boston book Silly Sea Sponge for birthdays, and the performer team based around Boston keeps the visit local: on time, in costume, ready at the door.

His costume is a lightweight, breathable suit with a textured surface built to hold its square shape through hours of dancing and games. The tie and shorts are stitched to stay put through a full round of silly dance moves, and the fabric is bright enough to photograph cleanly under any lighting, indoors or out.
Age-appropriate themed games matched to your character — from hero training to royal etiquette.
Simple cheek art or a temporary tattoo, included with every visit.
A high-energy dance-off your character leads with the guests.
