Siddhartha Olmedo, an artist for various JumpStart games, once posted a sketch to an online portfolio which seems to depict the JumpStart character Jo Hammet in a submarine underwater (top), since the face and hair almost perfectly match up to Jo's appearance in JumpStart 5th Grade (bottom). What's peculiar about the sketch is that it doesn't remotely resemble any scene in JumpStart 5th Grade, since there isn't a submarine and/or underwater exploration at any point. At the same time, this is the only game to use this character design for Jo, since she underwent a pretty significant redesign/style change for later appearances. This leaves it unclear as to whether the sketch pertains to some kind of deleted scene/scrapped content, either for JumpStart 5th Grade or a later game featuring Jo, or if it was for a game/project that ended up being scrapped entirely.
