i found them all.
IF YOU WANT TO FIND THEM ON YOUR OWN, PLEASE DONT READ THIS!
they are:
1: the slightly different colored spike after the frog gets pwned
2: the grey winged blocks that bring thwomp #2 back up after he falls
3:(gotta be fast) look to the left after thwomp #1 says, "now it's on" and you shoud see thwomp #2 (he'shard to see. make your computer screen as bright as you can) and keep your mouse on him. right as he says "pwned" click him a few times just to be sure.
4.(gotta be REALLY fast) thwomp #2's hand after he gets pelted into the ground by spikes.
5. thwomp #1 (himself) after he says "SHUT UP"(keep your mouse on him and when it turns into a hand, click on him.) it really funny. and when the guy says "90,000 pounds in the easter egg, he's not talking about weight. a pound is England's currency. so, he's saying he's rich. i THINK one pound is 500 american dollars. im not sure.
