Christmas Invasion is a mod that adds 3 new bosses in the game Minecraft PE 0.10.0 - 0.10.4 and the same, very interesting Easter eggs that will delight you. Bosses are quite strong, for example the boss "man cookie" already has 50 hearts, so be careful, rest is not less weak, consider this. That would cause every one of them, you will need to craft the spawn egg is very simple, but for each of them the recipe.
1. Man cookie ID 490
What would cause this boss you will need one cake and one egg from that game you get an egg spawn. After you defeat him you will be waiting a sweet surprise.
2. Evil Santa ID 491
This boss 2 times harder than the previous one and already has 100 hearts of health. Crafted egg spawn one diamond and one egg. If you defeat him, you will wait for interesting gift.
3. Boss (Easter egg) ID 493
This is the last boss, but it is not as difficult as the previous one, although that would kill him you still have to sweat a little. To trigger it you need to craft 1 snow block and 1 egg.
The only downside of this Christmas Bosses mod for Pocket Edition is compulsory to have a permanent Internet connection, otherwise the mod is very good.
