What the picture shows

A pink cartoon starfish character with half-lidded purple eyes, a drooping mouth, and a small drip of drool on its chin, wearing a black shirt that reads "I'M WITH", rendered in a flat 2D animation style against a pale green background. Chatters most likely use it to convey boredom, blank confusion, or a deadpan unimpressed reaction to something dumb in chat.

No measured meaning yet. Used 6 times in 2 channels this month; one is written once chat gives enough evidence.
