Justin, or known as "Big Justin", is an overweight toddler at the Golden Apple Daycare Center. At first, he seemed like a bully, but mostly because he's expected to be given everything he wants due to being the biggest one. He soon meets Tommy, both conflict over a ball to which Justin accidentally causes Tommy to fall back and knock down various things and ruin some of the kids things. This causes Tommy to be put in "time out" for five minutes. Impressed by how long he lasted in time out, Justin soon befriends Tommy and respects him. He, along with Wiseguy and the other babies, plan to escape out of the daycare. There he tells Tommy he wants to get out to see his mother again. No sooner that they try but they see Didi come to take Tommy. But as they watch, Justin wonders why he couldn't escape with him, but soon hears his mother come to him.
