In Magikarp Jump, the screen when you initially catch and name a Magikarp says the following:
Give your Magikarp a nickname!
- Maximum 12 characters
- Nicknames can be changed at any time
I've tried checking the records screen, game settings, and town, but I haven't seen any way to change my Magikarp's name.
How do I change a Magikarp's nickname in Magikarp Jump?
