Theoretically yes, but I don't think I'd be able to make it able to stick on nicely, especially if I don't have the mug that he'll be stuck to there to use as a guide for how to shape him. So I think that wouldn't be a good idea unfortunately.
You're welcome, he's absolutely irresistible..I might end up giving him all the milk I have in the fridge This would make a fabulous gift even for a hard core cat fan that doesn't even know what pokemon are
Mugs would be about 35-45 plus shipping, which will have to be a bit expensive because of how heavy and fragile mugs are. D: But if you're still interested feel free to note me and we can work something out.
