Celery

Celery is a type of vegetable that can be found growing in the Smurf Forest. The Smurfs generally use celery as part of their meals in mainstream Smurfs media.

In Salad Smurfs: The Movie, an in-universe horror film that is part of the EMPATH: The Luckiest Smurf story series, a random Smurf character turns into a celery stalk.
