Grooby's Up pose comes from Mokey's Show: Astroids, The down pose is from Mokey's Show: Math, and the left pose comes from Mokey's Show: 420.

Grooby apparently has a crippling drug addiction, specifically to Steroids (Asteroids), Meth (Math), and Weed.

Grooby also appears to buffer like a computer when overloaded with information, such as the various notes he hits during his song causing him to buffer on a left note (and subsequently do mini staircases) He also shows this by being able to bulk up both his mind and body instantly during his Down and Up poses, respectively. Grooby is, however, able to change his body shape seemingly at will, as he displays during the cutscene before Ah Hyuck, including various changes such as shrinking, tilting, widening, turning rainbow, and nearly withering away when he gags. However, he is also drawn just as crudely as Mokey and has varying facial expressions as well, although he doesn't appear to have the same level of control over his face that Mokey does, as only one of his poses radically changes his facial expression. Grooby has the same appearance as Goofy from the Mickey series, being a tall dog of some sort with black fur, peach skin, blue jeans, an orange shirt, brown boots, and a green hat with a black stripe.

Funnily enough, while Suicide Mouse's losing icon is darker than his normal icon, Mokey's losing icon is lighter than his normal icon.

Mokey's icon appears similar to Suicide Mouse's icon.

Mokey also appeared in Don't Starve as a mod.

Mokey's right pose references the 'Here's Johnny!' face from 'The Shining', and also has a real gun, possibly a reference to the April Fools Day video where Mokey accidentally killed Grooby and Dilan with an actual gun.

Mokey's left pose comes from Mokey's Show: An Abnormal Halloween.Mokey's Up pose comes from Mokey's Show: The Sun.The face he makes during his idle is considered his 'normal' face. Mokey also appears to be capable of changing his face at will, being able to scrunch it up and make it appear more detailed, or stretching it out to obscene portions. Mokey appears to be the same as the original Mickey Mouse, having black fur, peach skin, red shorts with yellow dots, and yellow shoes, but he is also crudely drawn, his shorts appear to resemble a diaper more. Mokey is a dumber version, of Mickey Mouse, Disney's mascot, and is also a parody version of him. “ oh! no we need to rescue the princess ”
