The idea sounds good, the voices sound baaaaaaaaad
When you see it, you think, "Hey, puppet cat Mario, puppet cat Peach doing a cute puppet show. Cool."
And then you hear it and oh my word please stop talking. I feel like companies are quite careful about their characters' personal brand, but put them in a catsuit and all that caution and canon goes out the window, I guess. Also, this is the European eShop -- the continent where ostensibly-Italian Mario is from -- and it's British accents?
If they're making a non-British accented version, I hope they let me voice puppet cat Peach.
