Bert is the forever best friend and roommate of Ernie. He is more serious than Ernie and quite analytical in their escapades together. Bert loves to eat oatmeal, play checkers, and hang out with his pet pigeon, Bernice. He also collects many things such as bottle caps and paper clips.
Ernie is mischievous and loves to play practical jokes on his good buddy, Bert. He has a big imagination and is very free-spirited. He is great at explaining things, but he often falls victim to his own jokes. Ernie enjoys singing, playing musical instruments, and most of all, taking baths with his Rubber Duckie.
