Looks alot like an actual Tekno dog. The one in this photo outside its box just has black ears,
a blue tail and a visor that isn't black like a real one.
I've never seen a yellow one, but it probably exists. This is the only photo I've seen of this knockoff.
They could be from the same manufacturer as Cartoon Dog. The blue Spotbot knockoff is based off
a color of Spotbot sold exclusively in Japan and the pink Kitbot is based on a Kitbot that was also exclusive
to Japan. The boxes for the Kitbot fakes seem to imply they play music, and I can tell the silver one has bump
and go wheels.
Looks like a McDonalds Chirpy-chi toy. Unlike the McDonalds toys, it's silver.
A bump and go toy that looks like it has moving feet.
The silver one looks like it has string on its back. It's probably just a sticker, though.
