I hadn't seen that. Interesting stuff. This certainly does lend more credence.I hope you don't still think this.

However, neither of those images can be taken as definitive proof. Yes, they kind of sort of look like a chipmunk Pokémon if you squint, and they very well could be, but the fact of the matter is that these are very indistinct images, and confirmation bias could be playing a big part here, as in we could only be seeing a chipmunk because that's what we want to see. And even if this is the rumored chipmunk, the fact of the matter is that real leaks often have fake info mixed in with them. This leak is looking promising, but it's still far from certain.
