isn't that one a cat?

yep thats the impostor :>
im curious was it too easy to find?

I wouldn'y say it's too easy, I guess I just know to spot something that feels odd xD

Oh and the eyes. Vague-ly slit pupils whereas the rest are round.

>:3c
this is so fun!

thank you :>

Eheh cool idea, very cool
Also i think i found him

Found it after a bit!

I think it's the catto? Since everything else is either a dog or a wild animal. Or perhaps they're all dogs, but some of them look like foxes, wolfs and other stuff. Or the odd one is the fox on the left because he's upside down :D
I like this format because it invites more thinking imho: it takes more effort to find out what the odd one is by examining them all to find a pattern

yeah its the cat, all others are canines in general
and im glad you think so btw, thats exactly the idea of this one! i do like the Spot the differences and Odd one out games but this one is a bit more interesting since as you said u gotta figure out first what the common pattern is for the majority of characters in order to find the impostor. it can be fairly easy like here but i wanna make more challenging ones in the future too :>
