Bonnie

"I never wanted to be an alicorn, I wanted to stay in Ponyville with you, mommy, and my siblings. But now, I'm a princess, and I won't be able to live in Ponyville." - Bonnie, talking to her father about her problems
Bonnie Diane Pie, also known as Bonnie Dian Pie, is the main character and the hidden Element of Compassion in the series Bonnie's Adventures. Originally, she was an Earth pony going to be a baker in Ponyville until Episode 20, when she became an alicorn and Princess of Compassion. She currently resides in Ponyville with her parents SpongeBob and Pinkie Pie and her younger twin siblings Strawberry and S'more. 
==Appearance==
Bonnie is half sponge half pony, also known as Spongepony. Her body is typical of a My Little Pony generation 4 filly made up of yellowish green sponge with a fluffy shoulder length pink mane and similar sized tail. She has bright blue eyes and a cutiemark resembling a cupcake with a whisk in a bowl to the right. Bonnie closely resembles her mother, Pinkie Pie, when she was Bonnie's age.
==Personality==
Bonnie is very bubbly and outgoing and appears to plan on befriending the whole world. She is extremely compassionate and is seemingly confident when it comes to her self esteem. Bonnie, however, isn't an angel, though, and can have her jealously control her actions in the snap of a finger. In a Non-Episode video, she grows extremely angry when a random filly is flirting and getting too close to Dusk. Spongebob was barely able to control his own daughter, and Pumpkin and Pound imply that multiple fillies have done this in the past and they should prevent telling Bonnie for as long as possible.
