.. Something angry

Yeah, you would need to distill angry into the drink.

Or, I would say to distill angriness into the drink. You know, the mood.

Have you gotten yourself a mood ring, already? ( Talk to Meowy at Meowy's Mporium. He will give you a mood ring. )

Activate the mood ring.

That means calm. So, if Cuddles licks the ring while he is not angry, the ring is only blue and would vaporize calmness.

You should get Cuddles angry. And, then lick the ring.

Lick the ring and use it on the hideous mug.
