During the April 11 episode of Community, NBC is throwing a GIFathon, where viewers are encouraged to create and post GIFs on Tumblr using hashtag #Greendale GIFs.

The best GIFs posted between 8 p.m. and 2 a.m. ET will win prizes, NBC exclusively told Mashable. NBC is trying to harness its viewers who are active on Tumblr to bolster live viewing of the “Intro to Felt Surrogacy” episode.

“Intro to Felt Surrogacy” features the cast as puppets and guest Sara Bareilles, so NBC is looking for for puppet-related GIFs. NBC describes the episode as such:

The study group takes a wild balloon ride that crash lands in the woods and they end up spending some quality time together with a friendly mountain man (Jason Alexander of Seinfeld).
