No betta should be in a 'teddy bear' that's just disgusting, that's not safe for the child because when parents buy that they know nothing! Yes nothing about fish, and say 'Awww, honey look how cute that is let's get it for little timmy" and of course the parents buy it when they don't realize the fish barely has ANY air in that stuffed thing, it could easily heat up and the fish could suffer especially on very hot days. The child would want to sleep with the bear, could drop it and break the bowl inside if it's glass even plastic. If the bear falls over wouldn't all the water pour out?
Another thing is, the tank will get filthy & disgusting, the fish wont look so good and the parents will be like "ewww, it not as pretty as it use to be" and don't even care about it anymore, and I bet the child wont know how to feed it or will forget to feed it. Honestly that's one of the most stupidest tanks I seen, and it disgusted me they are REALLY running out of idea's are they? Why can't they stick to making 3 gallons + into squares not 'fancy' crap.
