Uh oh, who's this little guy? It's obvious, he's the Herby's twin brother (despite he looks like has the same age as Herby's). He was created by a Tumblr user, britmef, in 2018. Sadly, this user gave not his name, but fortunately I can decide what name I give him: let's to see...hmmm...oh, I know! I call him Reginald! Okay, I downloaded that image from Tumblr, I watched him with attention and I made a fanart of him, utilizing Microsoft Paint.
