In an early draft of Gotcha!, Bonnie was going to appear on horseback throughout the film to add to the western vibe. It was going to later be revealed to be the family dog.
The red boots Bonnie wears throughout the film is an homage to the red cowgirl boots the director wore as a toddler and Ekon's outfit is an homage to the director's dad.
All of the background characters in the film are pre-established original characters of the director. In fact, Naomi and Heather (the 2 baristas in the beginning) were going to be the lead characters of another film idea that Gotcha! beat out.
The style of the backgrounds in the beginning of the film is influenced by UPA's style while the later backgrounds are influenced by Kim Possible's backgrounds.
