Nice toy... horrible stickers.
It looks like the sticker sheet was blown up a little because someone thought they would be too small for a kid to deal with... or too small for an adults thick fingers. All of the stickers are too big, so only half end up fitting.
I ended up putting some of the stickers in other spots just to add a bit more detail to the toy, but some were still wasted.
Nice idea, just ruined during execution.
