"Halloween!" is the Halloween episode of Oobi, produced for its third season.
Plot[]
The episode begins with Oobi dressed up as a dinosaur as he looks in the mirror practicing his roars. Uma is seen dressed up as a bunny. The siblings have each other guess what their costumes are meant to be. Oobi then invites the viewers to guess along. Grampu admires the costumes. He volunteers to take them trick-or-treating with Kako. Uma is excited because it's her first Halloween.
They arrive to Kako's house, where they talk with Papu. He gives the kids some candy, and Uma takes almost the whole bowl. Grampu explains that she is only supposed to take one. When Kako comes, Oobi asks he isn't wearing a costume. Kako tells Oobi that he's afraid of Halloween and that he's never gone trick-or-treating before.
Uma tells Kako that she'll help him overcome his fear. She takes the tail of her rabbit costume and puts it on Kako's head, telling him that it's a snowball costume. The kids and Grampu walk over to Mrs. Johnson's house, where they hope to get candy. Along the way, Angus is seen walking by in a ghost costume. Kako is terrified at first, but Uma shows him that it's just a costume and there's nothing to be afraid of.
When they arrive, Uma shows how to ask for a treat. Kako follows her lead and gets a box of raisins from Mrs. Johnson. She tries to guess what his costume is but she can't get it right. Shen then asks if it's a flower or a cotton swab. Kako finally says that it's a snowball. After each of the kids gets a box of raisins, Oobi waves "goodbye" to the viewers and the episode ends.
