Infant: Baby Bubble Lee was a “bubbly”, giggly, cuddly foal who loved being in the center of attention and being held by everyone.
5-7 (MLP Season 1): Growing up, Bubble was very head strong and independent, claiming that anything her male friends can do, she can do better. As soon as the “Cutie Mark Crusader” trend started to spread across Equestrian, Bubble was one of first fillies to pick up the banner and wave it high, dragging Cinderplume and Walnut around the island, finding new and exciting ways to get their cutie marks.
8-10 (MLP Season 2): When Bubble was 8, she fell down a sea cliff, and suffered a head concussion, causing her to lose all her previous memories. While everyone was happy to see that the filly was back home and safe, they couldn’t help but notice some notable changes in her personality. Bubble became more quiet and reserved, more observant of her surroundings and the ponies around her.
15-18: Despite her past, Bubble grew up from the cute, little, buck-teethed filly into a snotty, teenage-angsty brat, who thinks she knows best. She’s rather mature for her age and doesn’t like being told what do or how to live her life. Her biggest aspiration is the get out of her hometown and see the world. Also, side note. Bubble has braces and wears glasses up to around the time she’s 16. She doesn’t wear her glasses on a normal basis, she thinks they look stupid XD
21-25: After having a bad breakup with her coltfriend, Bubble was all the more determined to tell her hometown on the island goodbye. Bubble Lee started going to college at the University of Equestria, located near Ponyville (this is the future after all). Finally away from the sheltering wings of her parents, Bubble let loose and for the first couple years of her college experience, was really into partying and drinking and sleeping around with other college age students, getting herself into more and more trouble.
By the time senior year came around, Bubble had successfully fail enough of her classes that she wouldn’t be able to graduate with her class and was once threatened to be kicked out of the university if she didn’t get her act together. The reality hit hard and for that next year, she focused solely on her studies, leaving the party life behind. Despite her best efforts, she still had to take an extra semester to graduate. That summer before her last semester at college, she decided to go home for the summer one last time and by a random act of fate, ran into an orca pony hybrid who changed her life forever XD
26 and Up: I don’t really have much to say that wouldn’t be spoilers ;P At some point in Bubble’s future, Bubble does graduate, becomes a nurse and thats when the real story begins. Things to note that Future Bubble has short hair, but still keeps her curvy figure. On a side note, Two years after Bubble and Mako meet, Singe and Daniel meet, starting their story.
