Why would a narrator call it "regular" in this scene? Doesn't the word "regular" has the same meaning as "mediocre"?

You're right, "regular" does usually mean "mediocre". Here it has two meanings. The first being that "regular" is used as a description of an "ordinary" or "everyday" hamster. However, in this context, the word "regular" also means "traditional" or "classic" in a positive way to express awe or excitement. Ex: It's a regular quiz night! I hope we win! Ex: This looks like a regular old feast! I can't wait to try the food. Ex: Wow, look at this! A regular series of exclusive model cars.
