Speculations

Just throwing out things I've noticed while doing the event:

• Christmas Tree = 1 hit; has a chance of having 2 characters.
• Reindeer = 1 hit; either has 1 character hiding, or freezes you.
• Boxes = 3 hits
• Sacks / Shoes = 1 - 5 hits
• Every 5 characters found inflicts the other players with a random status effect / debuff.
• Every character in the first two stages gives 50 points.
• Each Christmas Elf / Humbugger / Rudolph in the last stage gives 150 points.
• Score does not affect rewards. Placement determines which reward you'll get.
• Freeze! Stop Right There! can bounce / ricochet off enemies in the last stage, stunning multiple enemies.
