Please help me brainstorm a evil name for my nightmare jester warador son 'Hoothoot'? He was a Noktoa before.

I still like the name Hoothoot.

Since some clowns do have honky horns as part of their schtick, Hoothoot is a sound your pet can still do. While it is a little outdated, someone who is lively and humorous at parties and social gatherings can be described in a complimentary fashion as " he/she is such a hoot". Just because your Nightmare jester's send of humor might be a little twisted and murdery shouldn't stop you.

Hop Frog was the name of Edgar Allen Poe's murderous jester. Pennywise is of course the first evil clown that comes to mind. Hecklar, Dimentio, & Laughlin are all good evil jester names... good luck finding the right one.

Somehow i keep thinking 'Cackles' ...

I second Cackles! Maybe Ludic? Slap-Happy? Snerks?

Hm, maybe Nocturne? Like Nocturnal?
