I bet this would be a fun game (though I didn't really like the gameplay in Yoshi's Island, but that was more because it was too hard than anything else). I really like the designs of the other background dinos; they fit the style nicely. Also, I would love to see Birdo and Yoshi in a game together other than a spin-off like Mario Party, Mario Kart, et cetera.
Meeeeehhh... Yoshi's Woolly World looks better now that there's more information about it, but I wish we had a Yoshi with skin rather than string in a big world to check out. There should've been a new console game for him years ago, soo...
True, last time we had a Yoshi game on a home console was Yoshi's Story. It's been a long time coming!! And while I wish Wart and Birdo and other dinosaurs like the ones I drew were included, I can't help but love the way Woolly World looks.
Well I figured each of them could come in any color, just as the Yoshis do. But if I had to add more dinosaurs, I'd probably add a stegosaurus, ankylosaurus, parasaurolophus, and a pachycephalosaurus. Maybe a velociraptor or t-rex, but I think Yoshi looks similar enough to those species for them to not be necessary.
