Lollipop is arrogant, snooty, and judgmental. She usually judges characters, such as Book and Barf Bag, based on their appearances. She also refers to others with nicknames, such as "Bagel Brain", "Sport Globules", "Tacoy", and "Little Gray Zig-zag". The nicknames seem to have a malicious slant, though it is possible that she sometimes uses these nicknames as terms of endearment. She seems to find it hilarious when others use her nicknames unironically. She's a grape flavoured lollipop
