Pete invites everyone to a Halloween party at the Trick or Treat Tower, but no one has come to his parties before, so Mickey and his friends try to fix that.
- Mickey Mouse - a magician
- Minnie Mouse - a witch
- Daisy Duck - Little Bo-Peep
- Donald Duck - a cowboy
- Goofy - a knight
- Pluto - a bumblebee
- A Jack-o-lantern light
- A garbage can lid
- A carrot
- A magnet
- Mickey: Oh boy! It's an invitation to a Halloween Party at Trick-or-Treat Tower. I wonder who it's from. (He opens the card)
- Pete: (Singing in the card) Pete is having a party. Pete is having a party. Everyone's invited to my big Halloween party, and 'course, nobody ever comes to my parties. So, why do I even bother?
- This is the third time Mickey had to be quiet during the Mousketools segment after "Mickey Goes Fishing" and "Donald and the Beanstalk", but this is the first time it was used as the last Mousketool.
- Donald and Daisy dressed as a cowboy and Little Bo Peep respectively are much reminiscent of Woody and Bo Peep from the Toy Story film series.
