I don’t know the title, but I checked it out from a local library in McAllen, TX about 20 years ago. It is a children’s book with pictures on every page about a small animal (like a hamster or gerbil or mouse?) who travels the world while floating in a bubble. I think the cover was dark blue or purple, and I believe one of the places he went was Paris. I apologize if this isn’t enough detail, but its all I remember. I had it checked out the maximum amount of times and want to own it now for my own kids.
Thanks for your help.
