Role in the film
Like Stinky Pete, Señorita Cactus did not like children and wished to be kept on display rather than being played with. In the original climax of the film, Buzz and the other toys would've hijacked Al's car while he was preparing to leave for the airport and tried to get Woody out of the trunk. Señorita Cactus and Stinky Pete would've tried to stop them, only for them to fall out onto the street and get picked up by two kids on bikes.
- "Señorita" means "Miss" in Spanish. This likely means her name is "Miss Cactus".
