Bump N' Go Cartoon Dog is a knockoff Spotbot by an unknown company.
The toy looks almost identical to TOMY's Spotbot.
It's only known to have been sold in a white and pink color scheme, and in a white and blue color scheme, but the box has a photo of one that comes in yellow and blue; they don't come in the same colors as the official Spotbots. These dogs have a green patch on their left eye, and they appear to be missing a little ridge below their eyes, that TOMY's Spotbots have. In contrast to the official toy they have a colored patch on their backs that matches the color of their muzzle, and their eyes are red, and closer together.
Unlike the original toy, this one is a bump and go toy. This means, if it hits and object while moving across a surface, it will change directions.
Aside from bump and go action, I don't know for sure if it barks or plays music, and if it is capable of moving its head, tail, and legs. Its eyes looks like they're meant to glow.
