My friend Andrew made up Abba AND Bubbi, and they are both supposed to be three years old. Abba is taken off of a song in a psalm book called Abba! Father, and Bubbi was taken off of the nickname that Manny gave Greg in Diary of a Wimpy Kid. First thing you need to know about Abba, he likes anything fuzzy. First thing you need to know about Bubbi, if you do something he doesn't like, he'll "pinch you until your blood comes out!" Abba was run over by an Oreo truck, and Bubbi was hit by a derailed train.
