Mobi's activity started under the Newgrounds account, Mutteo, producing a small collection of Flash animations from 2008 to 2013. In 2009, he began to upload NSFW shoe-fetish content to his FurAffinity account and strictly SFW content to his DeviantArt account, under the same name of Mutteo_Cleafurry. Around 2010-2011, he created a new DeviantArt account, Amazing Mallard, uploading suggestive content that bridged the gap between his two accounts and now signing them as Mathew P Cleary. Mobi would disable and delete his Fur Affinity and original DeviantArt accounts just months after announcing his retirement from Flash Animations on Newgrounds in 2013. Mobi continued to upload safe and suggestive content to his Amazing Mallard DeviantArt account until 2018 where it was once again deleted but replaced it with a new account, along with brand new Twitter account, 2oonscap3. Some of the old content was reuploaded to the new 2oonscap3 Deviantart account but a large collection of questionable and NSFW content remains lost.

Mobi now predominantly uploads SFW content.
