Yucchy! Yucchy! is a 2008 Sesame Street book featuring Oscar the Grouch and Slimey.

Oscar and Slimey love yucchy things, and they decide to find out if other people do too. Grover is walking in the rain, but he still feels like singing. Elmo and Zoe enjoy finger painting. Cookie Monster is covered in delicious cookie dough. Ernie, Bert and Big Bird are getting sweaty as they run and ride bikes in the park.

Finally, Slimey sees Ernie and Rubber Duckie getting cleaned up after a dirty, sticky day outside.
