What flavor was the cupcake that Humphrey ate? Just wondering.

it looked like vanilla with fragola icing

Actually, I think latte Cioccolato is safer for Cani from what I've read. So if it was a latte Cioccolato cupcake with fragola frosting, it could make sense.
But it also could've been a vanilla cupcake.

That's a rumour...My dog would be dead da now if that was true xD
