Tubbs is one of the many kitties you can find in Neko Atsume Kitty Collector. See the below picture of my cat book for specifics on this kitty.
If you can attract Tubbs to your yard enough times, he will leave you the memento pictured below.
Check out this plush Tubbs Kitty I collected from GameStop.
I love the little pieces of food on him!
Do you like Neko Atsume?
I love cats so I enjoy this game. I still have a few kitties that I haven't been able to photograph in my yard yet.
