Pee-wee wants a letter mailed, so he asks Jambi to make Reba appear at the Playhouse. This makes Reba mad because it's her day off. Pee-wee convinces her to stay for an imaginary breakfast of oatmeal and potatoes. Meanwhile, Pterri disappears when Pee-wee sends him to his nest for being naughty. The Playhouse gang blames themselves for Pterri's punishment until Pterri comes back - from hiding underneath the bed! Watch, "now," and you'll have a "Pterri-fic" time!

Pee-wee has to eat his words when he tells the gang how important dental hygiene is and, then, develops an ow-some toothache! Since Jambi is taking a head-turning vacation at Mount Rushmore, Pee-Wee is forced to face his greatest fear - the dentist! He's so afraid, it'll take Miss Yvonne's coaxing just to get him to go. When he finally does make "it," Pee-wee learns that visiting the dentist is nothing to grit his teeth over and can actually be fun.
