Writer Revolt: "Topped With Buttercream" sure comes off this way. It's undoubtedly meant to promote the candy-themed LPS toys (which seem to be half the toyline), but it's not flattering to the concept at all. Characters mention off-hand the detrimental effects of a diet rich in sugar. The pets get high on sugar and turn into twitchy, paranoid, delusional savages. Buttercream seems to have been permanently damaged by sugar to the point where she has multiple verbal and physical tics. By the end of the episode, the pets run in fear from sugary snacks (although they get over it in future episodes).
