Malcolm's first appearance was in Don't Hug Me I'm Scared 3, when Shrignold and his friends took Yellow Guy to where they worshipped him. He orders his followers to feed him gravel, or he becomes angry.
Malcolm is the 'King Of Love' in the 'Love-Cult', the collective name for their clan
- On the credits of Don't Hug Me I'm Scared 3 it shows Malcolm's head burning behind the text. You can also see a gas can, with the logo from the monster from the HELP videos.
- Malcolm makes a cameo in DHMIS 4 as a little desk prop, but it isn't on the table where the puppets are sitting at.
- It also appears in DHMIS 6 (as a desk prop and animated).
- He faintly says, "Mmmmm.... Gravel..." in DHMIS 3.
