Play the cool christmas-themed sequel of the funny action game Effing Worms and help the caterpillar to guzzle everything that moves in order to become larger and stronger. Mission is to catch and eat up the thick Santa Claus. Start as a little worm and become bigger and bigger each level by just eating everything in your way.
Munch yourself through the underground and jump up whenever you see a potential victim. Try to eat several santas at once to get even more points. You can upgrade your hungry caterpillar after every level to make it more efficient as you proceed. Enjoy Effing Worms Xmas online and for free on Silvergames.com!
