[@Real_KylieYT]

Happy Halloween 🎃 👻

[@MarioFan-xq6jo]

Truth be told, I wanted to wear my costume to my school for their annual festivities on Halloween every year! But unfortunately, not only was the festivities yesterday, but there’s also this policy of where you’re not allowed to wear a costume ahead of time before you arrive, the problem with my costume is that it’s mostly make up! Therefore, I had a problem! Not just with the costume, but also with my mental health! In other words, Happy Halloween!

[@thepra600channel2]

7:13 Is that supposed to be a real flying broomstick Carolyn is floating on?

[@CooperCollinsTheAnimator]

No. There’s rope attached to the wall with thumbtacks, attached to the broom for her to pretend.

I forgot to ask you one question. In the video, why does is Marcus still pronouncing Caillou's name as "Kayloo" even with Steven's voice? Why not like the pronunciation in the original TV show and like Cameron did?

@@tylerhinkle2005 I was also thinking about this one, and it is also a Christmas party. Cooper’s Surprise Party A.K.A. The Treehouse Club's Big Christmas Party The club, Principal David, Carolyn, Coach Davis, Tony, and Kristi are all setting up for Cooper's party and surprising him. While setting up the party, some people are getting some stuff like party supplies, balloons, pizza, and other snacks and food. Some foods are getting baked like cake, cupcakes and cookies.
