Characters Present


In this episode, Steve and Blue get prepared for Mailbox's Birthday. Mailbox has just turned a decade old.


For Mailbox's birthday, there's a special celebration and we are invited to help out. They help decorate the cake for the party by observing patterns. They also skidoo along with Steve and Blue into the present store. There, they find the perfect present for Mailbox, which is a stamp book and then help Blue & Steve to find it when it gets lost among a bunch of other presents.


  • This is the first episode in which Mailbox's voice actor Seth O'Hickory is credited in the closing credits to this episode.
  • Steve's rugby shirt near the end of the episode seems to have a slight color alteration, as if the darker green stripes appear to be blueish-greenish.
  • This is one of three episodes revolving around a character's birthday. The other two were Blue's Birthday and Joe's Surprise Party.
  • Since Mailbox was ten years old in this episode, we know that he was born in 1986, and nine years old in the first two episodes. By the end of the series, he should be eighteen years old as of the Season Six episode Bluestock.

  • This is the third episode of the show.
  • Steve says "Ah-ha!" in a squeaky, funny, high-pitched voice.
  • This is the first time where Steve gets the mail at the end.
  • Steve temporarily cries after thinking he's sitting in glue.
  • This is first episode where viewers say "Notebook!" where they sound like they are screaming. It was used on most episodes for Season One to Three until Signs.
  • Blue's rubber duck first appears in this episode as one of the toys at the present store.
  • This is also the first episode where Jennifer Oxley was one of the animators.
  • This is the 3rd episode of the show.
