Backround story = It was Christmas eve, every survivor started to open their hard earned gifts. Thus came the red gift, the hardest one to acquire. As the survivors started to open it, they saw a miniturized version of the once almighty ,,Frosty Jr.. It was said that Heavenly Day manufactured and geneticly modified the once big snowman into a miniature sized one, but that was never confirmed.
Mount = The mount has 2 specials abilites one of them is a throwable hammer, as seen in the Frosty Jr. boss, the second special ability is a Thor Mode and it's the same as the one is Frosty Jr. boss.
Mount statics =
17 = speed
35 or 38 = jump
60 to 70 = damage with throwable hammer
20 to 30 = energy to throw the hammer
Normal mode stats
19 = speed
30 or 32 = jump
110 to 120 = damage with throwable hammer while in Thor mode
35 to 45 = energy to throw hammer in Thor mode
Thor mode stats
To enable the thor mode press F and a little animation will play (or not if pr choses) and ur Frosty's appearance would change. He would get Blue glowing eyes, thus a electrified hammer with blue glowing effects.
Edit 1: When thor mode is enabled the hammer would electrify the zombies that are shot with it, so if the hammer dosen't kill them they would stay electrified on the ground for a couple of seconds.
Hope you liked my suggestion (and a speculation)!
