The Toledo Bullfrogs was to be a professional arena football team based at the Lucas County Arena in Toledo, Ohio. They were scheduled to begin play in the af2, the developmental league of the Arena Football League, in 2010, until that league folded in 2009. The team never played a game and the Toledo Bullfrogs website now leads directly to the Toledo Walleye website.
On November 18, the Bullfrogs announced their name, logo, and colors. The name was chosen as an homage to the city sitting on what was formerly the Great Black Swamp, ergo, when the city was founded, there was a frog infestation. This heritage is also immortalized in the Lucas County Courthouse and Jail, where a frog is depicted in the floor mosaic.
