When I first saw it advertised they where doing an uncle grandpa crossover I wasn't very happy I thought they where going to screw up the best cartoon series out there with one of the worst but the fact that there kinda writing it off as an April fools and not really part of the show helps a little, yes there where some funny parts to it however they made Pearl way to animated and insane which I didn't like at all I did like how they weren't just OK with uncle grandpas presents and treated him as some insane powerful being that must be stopped instead of just knowing who he is and being ok with whatever he does (though Steven knew him which made no sense) basically there styles are way to different it was a strange show to crossover...........but thats just me
