Continuity mistake: When Starfire is force-fed pie by Mother May-Eye, she swallows a rough clump of pie before pretending to be mind-controlled. But after may-Eye leaves, her tongue evicts a whole pie from her mouth, plate and all.
Suggested correction: It's not hard to believe that Starfire's tongue has the ability to retrieve things from her stomach. As she is an alien who has multiple stomachs and many strange qualities.
