At some point in development, it was named Mudslacksu.
Parts of it, like the spikes and ears, seem to be based off of Sonic the Hedgehog. The shiny is based on Sonichu, or Super Sonic. Overall Mudslacks may also make reference to the abundance of poor (or "shitty") Sonic fan art on the internet, but could also be relevant due to the creator of Sonichu, Christian Weston Chandler aka “Chris-Chan”, having admitted to soiling himself in an attempt to cause an “information overload”. This may also make reference to his “shitty” drawing and art style. Furthermore, its Shiny is yellow, making it similar to Sonichu.
Mudslacks is a combination of mud and slacks, a synonym for "pants".
