To see what it can turn in to, check out Rivenn's Tamadex V2. Click on what toddler you had, then click on what teen you have (Ufotchi) and you'll be able to see what it can turn in to!! .
I am no expert but what I have learned is there are many characters your Ufotchi could evolve into. Mine just evolved this afternoon into a Mametchi...this is my first Tama and I have been so careful with her...I am so happy to have this fun-looking character...she hops around and then gives you the biggest grin... I haven't been able to plat with her yet but she looks like she is happy and likes to play. She changed from Ufotchi at 4 yrs and full training as of last night.
Here's hoping whatever yours changes to is fun and active
