Hey im going to tell you 5 funny ways to troll your friend in minecraft.

1. Lava - when your friend is sleeping in their minecraft bed place a bucket of lave over the bed, they will not die immediatly but as soon as they exit the bed they will burn to death.

positives - funny, your friend sits there for a few minutes even if they dont exit the bed at dawn they will be kicked out.

negatives - lose your friends items, can cause them to disconnect and not join again.

2. Pressure Plate TNT - A very common but often badly done trick, the best place to put your TNT under a pressure plate that activates a door this will probably wont kill them but it will cause destruction in their house making them have to rebuild.

positives - your friend has to rebuild all or part of their house.

negatives - often cause retaliation and probably won't kill your friend

3. Nature - when your friend is not online plant trees in wierd places and place dirt everywhere and bone mea the dirt make their house look overcome by nature break random blocks.

positives - easy to do, hard to fix

negative - can make them want to do it to your house so dont go to over the top

4. TNT cannon -build a TNT cannon pointing at there house and make them give you items so you dont fire and if you want fire anyway.

positives - can get you more items

negatives - can miss the house

5. Lighting Problems -take away all the lights in thier house and you can repeat this making them have to clear out mobs and creepers can even blow holes in thier house.
