Dance move or a static emote similar to the Most gentlemanly emote.

Hair wasn't mentioned last year as a reward but could be purchased from a vendor during the event. for 20k MGP if I recall correctly (Def could be bought as that's when I got it) So might be the same this year. No mention but will be in the MiR event vendor.

and the Games can be bought already. I think theyre in Prize II of the vendor with the 2m MGP mount etc. They're priced at 500k. This event will no doubt just let you purchase it for 300k which I think was the price last year during the event.
