Because his model is only edited promo art, Wubbzy Weegee can always be seen striking the same pose, with outstretched arms and a curled tail. While Wubbzy Weegee's exact origin is unknown, he is shown a few times throughout the 2014 Halloween special, and is only used there for comic relief.

A fan of SMG4's bloopers and contributor to SM64: War of the Fat Italians 2015 (600k Special), SwagKirby, designed Wubbzy Weegee years before HalloWeege was released (and a year before SMG4 made his first blooper). He was referred to as 'Wubby' in the first few months of the Wubblog before a post was made on July 19, 2005, when the blog announced that he would be renamed 'Wubbzy.He was incredibly grateful for SMG4 using his work in his video and even made a video response. However, he later appeared in Mopsy, Flopsy, and Ted!, retaining the name but being referred to with male pronouns and appearing much like the television series. He was referred to with female pronouns and had a much rounder shape with a shorter tail. He was named 'Mopsy.' He looked different from the comic and the television series. Wubbzy first appeared in an unpublished comic book by Bob Boyle and Viviana Ogawa titled The Tail of Flopsy, Mopsy, and Ted. Wubbzy's last appearance was in Woozy Walden, the series finale of the show.

Wubbzy made his first appearance in the pilot episode, A Tale of Tails. He is the only one of the 4 main characters to have appeared in every episode. Wubbzy has appeared in every episode of Wow! Wow! Wubbzy!, as he is the title character. He has 2 average-size arms and 2 round feet attached to small legs. Wubbzy has 2 short ears sticking out of the top of his head and 2 hands with 4 fingers on each. He has 2 black eyes and a long, bendy tail. When he sees a third astonishing item, he says 'Wow' three times, 'Wow! Wow! Wow!'.

When he sees the first item, he often exclaims, 'Wow!' When he sees a second astonishing item, he yells, 'Wow! Wow!'. This usually happens when he spots three astonishing items in a row. Wubbzy also says, 'Wow! Wow!' in excitement. He also uses it to greet the other characters, though sometimes he says 'hi' instead. He often uses it as a greeting to the audience at the beginning of each episode. Usually, when something terrible happens to him, his friends always help him out. He loves playing with all of his friends, and his favorite sport is kickety-kick ball. His other friends are Huggy, Buggy, and Earl. Wubbzy lives in the town of Wuzzleburg and has fun with his best friends, Widget, Walden and Daizy.
