Throwing out some keys

Well only a few more days untill New Year and i have a few keys that need to be used quickly
So here you all go:

This is not a steam key but has to do with this: https://mcchampionship.com/
MCC Island (Minecraft Java Edition):
Jingle Jam Rewards pack!
Redemption Key: JJ23-9722-DD7C-PY6D

This one is a DLC
PlateUp! Cosmetic DLC
Look Good While Cooking
Redemption Key: R46WI-7C8QX-4382D

I'm unsure if this is the full game or if this is the 'Complete Bundle' DLC
Run Prop, Run! Complete
Bouncy Prop Hunt
Redemption Key: 6JZGV-HKTFA-REHET

This is an old key unsure if it is still usable:
Unity of Command: Stalingrad Campaign
PTJMP-TN2PN-0AKQW

Anyway Happy New year everyone and hopefully i'll be a little less lazy and make a train next year.

Here is on more i overlooked before it seams:
Cook, Serve, Delicious! 3?!
Cooking Typing Management
Redemption Key: ECBYG-B9XK8-MF442
