Tower Defense Design

[hamster mk 4]

I have been asked to make a Christmas themed Tower Defense game, and am drawing a blank on what the towers should do. I know the basic answer is ?kill stuff? but the joy of a tower defense game is killing stuff in interesting ways, also in how the towers compliment each other. In all honesty I haven?t played that many tower defense games and I don?t really have the patience right now to comb the internet looking for the good ones.

So I am asking for inspiration. What would you put in a defense tower? What would it do to enemies? How would it work in conjunction with other towers? What sort of enemies would it be strong against? What sort of enemies would it be weak against?

Frosty the Snow Man with a freezing attack, normal damage + slowing enemies.

My advice is to cheat, play Plants vs Zombies then just think up fitting reskins for it.

The snowman idea is a good one.

I already did the Plants vs Zombies cheat on a different game. I want to try something new, which is why I ask.

I especialy like the bauble tower being the low end spam tower, the sound effects alone would make it awsome.
