Sugar is timid and likes reading books to learn. When his parents are unable to do so, he often tries to assert rule over Spice, to no avail.
Sugar was born of Patrick T. Cake VI and Bebe "Big Bull" Cake in the Old Chateau in Eterna Forest, in Summer 722 AE, roughly one hour after Big Bull went into labor and two hours before his sister Spice was born. A few months after the family left the Old Chateau, Sugar returned with his sister Spice to clean up the mess their parents had made, some of which they claim "tastes like strawberry jelly".
Later on, Big Bull brought the family to the Hoenn Battle Frontier to test their battling capabilities, but Sugar wanted nothing to do with it. Instead, he sabotaged his family's efforts to make sure that none of them would win so much as one Frontier Symbol - and he succeeded, for the most part. Sugar's parents thought it would be a good idea to go vacationing at Floaroma town...until Sugar started arguing with his sister over whether sweets or meat is more important. Despite his sister's rebuttal, Sugar asserted that sweets are more important. Patrick decided to settle the argument with a bet - he would go a year without eating sweets, and Big Bull would go a year without eating meat. Of course, Sugar would bet on Patrick losing, but the bet ended in Spice's favor when Big Bull caved at the hotel in Hearthome City.
Upon hearing that there was going to be an attack on the hotel, Big Bull grabbed Patrick, Sugar, Spice, their stuff, and ran back to Goldenrod
like a little bitch, presumably to go back to a standard everyday life.
While most of Sugar's capabilities are currently unknown, he and Spice have a higher tolerance for cold climates and a lower tolerance for warm climates than most Snubbull.
