Adventure Time OC

That's right. Deal with it.

TL;DR: Cleo, shape shifter, must find lost memories
---
Name: Cleo (real name: Anise)
Nicknames: Shifter Princess
Talents: shape shifter (only into animals, no partial shifting), sings, plays the {instrument}, can use magic (sort of)

Back story: Introduced with little memory, she seeks Finn & Jake's help retrieving her lost memories from around Ooo.
She reveals that she knew Prismo, and that he helped her get this far. According to Prismo, she says, she had been sucked into a dimensional rift and flung throughout 8 dimensions until eventually landing in Prismo's fixed dimension. Being tossed around dimensions had caused her memory to fragment and scatter. Like Jake in the process of making her wish she befriended Prismo. "I wish I could find my memories" was her wish, which Prismo criticized for not being well worded but that he'd do his best to not make it too hard. Her memories were gathered from the 8 dimensions and condensed into 8 memory fragments, which were scattered around Ooo for her to find. Prismo invited her to stick around for a party he was having later, but she insisted on finding her memories right away (the same party Jake is at in "Wake Up"). She appeared on Ooo with a small pink messenger bag containing a jar of pickles and a note saying "When you've found all your memories, come hang out sometime  -P."  She has already found one memory, containing her shape shifting control, which she found after spending some time in the Box Kingdom.

-Example of initial interaction/intro episode-
Finn: "So, you've got a shiny on your forehead; are you a princess?" Cleo: "I don't know." Jake: "You definitely look like a princess. Let's give you a good princessy name! How about Alexandria? Or Catherine?" Cleo: "Um, no." J: "Regina? Elisabeth? Cleopatra!" C: "Um, how about just Cleo?"
Through the episode the trio discovers a few of her memories, but not all of them. She discovers, however, that she only seems to be able to find them when she's not looking for them (when she's having fun, distracted by something else, etc). At the end of the episode she decides it's ok that she doesn't have all of them right now - she'll just explore Ooo on her own from then on and see what happens. Future episode(s) can be finding more &/or once she's found them all.

Memories:
Shape shifting abilities, Instrument, Time in other dimensions, Society (where she came from), Name/Identity, Family, General Life, Dimensional/Magical abilities
Through the Name, Family, and Life memories she remembers that she is NOT actually a princess, but the nickname sticks and she is eventually given an honorary "Princess" title.

There's more details, but you don't care about that. Unless you do; then I'll tell you.
