Need help with what can be done with our Mustang and need help with a filly name?

A family friends 4 yr old granddaughter named (@ the time) her grandmothers filly Sautika (sawTkah). The 4 yr old is really rambunctious, ended up that the filly is also. 2 yrs later, it still fits her. She's a beautiful blue eyed, white & blue filly, still hyper & all :D What I loved about the name the most is how unique it is. Her mothers name's Maybelline (like the makeup). My horses name's Lucy. Since she's 14 I decided to keep it just add a little to it (bought her in Nov) I kept calling her beautiful & Lulu so I changed her name to Beautiful Lucie LuLu, most of the time every1 calls her LuLu :D My 1st horse was named Corizon (heart, sweetheart, etc) but since I was so shy about speaking spanish around people my grandmother told me I could just call her Sweetheart. She also had a horse named Chica, that was still very rambunctious in her 20s lol. Wish I could've been more of help, best of luck!
