RE: Toys Reveal New Pokemon?
To be honest, I don't think that the Larvitar-clone looks like a pre-evo of the Picture above.(Yellowish green.)
I see more yellow in the thing around its neck than green. I don't see green at all in it. Though there are some resemblences, they are WAY too far apart for me to judge. Maybe the brown one will be another pseudo-legendary like the other Gen-specific Dragons and Ono will be another pseudo-legendary of the generation. Unless proof comes out, or any artwork, I'm sticking with no relation.
As for the monkey, I think it only shares color with the Gummy Bear.
