Susie

Susie is a young girl, ranging from 14-16 years old. She wears a pink t-shirt with an orangish-yellow heart over where her real heart would be, periwinkle shorts, and yellow socks. She has a round head with long brown hair tied into a large ponytail with a yellow hair tie, with a widow's peak on her forehead and two long strands in front of her ears that end pointing off to the side at a ninety-degree angle. When livestreaming, she wears a pair of pink headphones with black speaker pads.

Pictures of her as a younger child showed her looking mostly the same, but with a much shorter ponytail and rosy cheeks.

Because Susie is almost exclusively seen around Pump and Skid, much of her personality when in surrounded by people she actually likes is unknown. In the presence of her brother and his friend, she is often snarky and rude, shown in Spooky Month 4 when she tells Pump "no" before he can even ask his question. Even after letting him finish, she still tells him "no" without a second thought and slams her door in his face, even though all he wanted was some colors. After the two of them steal the colors anyway without her noticing, she barges into Pump's room without knocking and angrily demands to know why he took them despite him trying to ask earlier.

Susie seems to be far more respectful, kind, and cool-headed when not near Pump and Skid, as every time she interacts with Lila she is extremely nice and easygoing. While this could just be a case of respecting her elders, it is more likely that she actually enjoys the presence of Lila, since she is an adult actually capable of keeping Skid and Pump in check. Susie is also very calm when livestreaming, although she did lose her cool when Skid and Pump broke into her room.

Her angry attitude towards her brother seems to have only developed after her parents left them in the care of their grandpa, since family photos around his house show that her and Pump initially got along very well. It seems her opinions on him soured once there was no longer anyone around to keep him under control, and she became a sort of secondary guardian to him. She still cares deeply for Pump regardless, even if she doesn't show it often. When he comes home shivering after getting his coat stolen, she tells him to get comfortable on the couch and makes him a mug of hot chocolate to make him feel better.
