block world (gm skill) - the skill basically places a block where ever you place it. if you click on an already spawned block, it will remove the block prop (logged from g20)
stop right there! (event skill) - it stuns everything. must have the event hammer to use this skill (logged from g20)
using exploding toilet paper - basically a B-bomb. used without mobs first, then used on mobs (logged from g20)
using a pet whistle - from the coffee event
playing tennis bingo - from the new bingo event. oddly enough using the bingo card item doesn't send any packets, so it's client sided (seriously why is it not just an event button instead of another item >_>)
