Btw here's my characters' backstories if anyone's interested:
Sherb and Strawb are brothers.
Their father abondoned them when they were babies and their mother couldn't take care of them, especially since they lived in the Multidimensional void where it was very dangerous.
So their mother sent them to foster homes in different dimensions.
Sherb lives in the Mushroom City Dimension.
Strawb lives in the New Donk City Dimension.
JetMcSetter is actually an associate of their mother and is looking out for both of them.
