That sounds hilarious! XD Do you know any servers that allow mob disguise for all players? I'd love to play pranks like this on a server, but each one I find requires you to pay for it. :C

My freind 123lump in his house. I walk in as a creeper, place a block of tnt, light it, and run away.

I pretended to be a chicken on a skyblock server I'm mod on, and so this guy was like, freaking out, cause chickens, or any animal, are rare on skyblock, so I derped and walked around awkwardly, like any old chicken. He fenced me. And then I started shooting arrows at him but only when he wasn't looking. He got so confused. Then eventually I broke the fence and walked out, and he freaked out, then i walked off the edge and he started swearing in chat. :D

mob disguise server?

i am an owner of a sever i use /md to see what the other people r doing when noones watching

I used mob disguise and became a squid, I then proceeded to swim in lava and shout LAVA SQUID!

My friend joined in and mob disguised as a squid too, and started flying around letting loose lightning bolts while screaming LIGHTNING SQUID!

Everyone was dieing from laughter

I was disguised as a cow and flew down next to a couple of cows on the ground. I pretended to be a real one and walked around stupidy and jumped a lot. Eventually a player came by and surrounded me with fences and gave me water and stuff. I had to pretend to be a cow for a while. Eventually she tried to make me bread with another cow (oh yeah) and it didn't work. So she killed me :D
