However, we can make some educated guesses:
* Jennifer Lee, the screenwriter and co-director of Frozen, was heavily involved in character development and likely had a significant say in choosing the name.
* The creative team at Disney Animation, which included animators, artists, and other storytellers, would have been involved in the brainstorming and decision-making process.
* Possibly, the name was chosen based on research and market testing, to ensure it resonated with audiences.
It's important to remember that moviemaking is a collaborative process, and the final decision on a character's name would likely have been made by the entire team.
