Stinky the Stinkweed

From Muppet Wiki

Stinky the Stinkweed is a living stinkweed from Sesame Street. At times he's a bit self-conscious about his smelly lot in life, but he's generally a very friendly plant. He doesn't hesitate to ask for a favor, "If it's not too much of a bother."

Stinky first appeared on Sesame Street in Season 25. Episode 4049 of season 34 featured Stinky, when he and Zoe write a story together, with Gordon's help.
