Sketchbook is a small, white notebook. Sketchbook has rainbow colored hair that can only be seen once in the entire series. Sketchbook has two short, black arms and always has a pencil in their right hand. When asked about Sketchbook’s gender, creator and director Joeseph Pelling said that it was paper.
Sketchbook encourages the gang to be creative. She seems to dislike Yellow Guy the most, since he is the most creative of the three. Sketchbook thinks that green is not a creative color, and doesn't measure the best learning methods. According to Pelling, the message of DHMIS was "how not to teach something".
- "What's your favorite idea? Mine is being creative."
- "I see a silly face, walking along and smiling at me!"
- "Listen to your heart, listen to the rain, listen to the voices inside your brain."
- "'Cause you're not thinking creatively!"
- "Green is not a creative color."
- "Come on, guys, let's get creative!"
- "Maybe to you, but not to me."
- "I use my hair to express myself."
- "Now let's all agree to never be creative again."
- "Come on, take another look."
- "Woah, there, friend! You might need to slow down!
- "Now lets all agree to never be creative again!"
- Sketchbook makes five cameos. Once in the second episode when Red Guy is in bed in his room and there's fish everywhere, once in the third episode when Yellow Guy is being joined into The Love Cult, once during the HELP video, and twice in Don't Hug Me I'm Scared 6.
- Sketchbook is often called "Paige the Notepad" by fans.
- In the end of Don't Hug Me I'm Scared 4 there is an oats box that has Sketchbook's face on it on the Fake Set.
- In the very beginning of DHMIS 5, when Duck Guy picks up the phone, Sketchbook can be seen behind the phone buttons.
- Near the beginning of DHMIS 6, when Yellow Guy starts walking down the hallway with the lamp, you can see the Sketchbook in the first picture on the wall.
- Also In DHMIS 6, when the Red Guy messes with Roy's control panel, it is revealed that Sketchbook was the only teacher that Roy did not come up with, as evidenced by the fact that it does not appear when the teacher changing sporadically.
