Kids shows I have faint memories of.

I have memories of a show that looks like “peg + cat” except I remember them going into a book corner and jumping into the book for an adventure. I might be combining two shows together or miss remembering. It might be “peg + cat” but idk if it is. I also remember this other show about a little creature and a girl. All I remember is an episode where the creature wears a robot costume for Halloween and the girl and their friends think they are a real monster. I remember a part where the creature is behind a bus, but the background was just a white space. If anyone can help me find these shows I would be so happy.
