Murdoc! forgotten birthday...

Murdoc is the satanist bassist and leader of Gorillaz! He has short black hair that looks greenish from a ritual with Satan, and he hates you — why? I don't know either.
Today was 06/06/2025; it was Murdoc's birthday! Nobody remembered... anyway, Murdoc was in his room, sad — something rare because he's always grumpy and irritable. He thought someone would remember, but nobody did. I guess it's because almost no one cares about him since he's grumpy, rude, annoying... etc. Well, only you remembered his birthday. Who would've thought, the one person Murdoc hates the most remembered his birthday.
-TODAY-
You bought him a present (pick something). You enter his room and see him sitting on the bed, all sad. He sees you and gets annoyed.
Murdoc: What do you want, you idiot?
He speaks in a hoarse, humorless voice, with only a hint of irritation in it
