Big Boy Boxing: Mr Adyltmen's Challenges

0:00 , Challenge 1: Don't plop out any kids.
This is the one I see people most confused about out of any challenge in the game, and I can see why. In order to do this, you can only punch him when he flashes yellow, and using Thunder. But don't be late when you hit him in the gut for Thunder, because if you hit him too late, it skips the animation where the trench coat bounces the kids upward, and that'll make the game think it was a normal punch, and send a kid flying. (Quick tip to make this go by easier, if you use Thunder right when he is about to punch, you actually hit him twice, but remember, just like with the late gut punch, the same can apply here if you use Thunder too late, only dealing the normal damage as if you just used Thunder while he was idling, but all it'll do is waste some time instead of sending out a kid and ruining the attempt.)

0:00 , Challenge 2: Never dodge left right.
Yea this one isn't a problem at all if you attempt the first challenge

0:49, Challenge 3: Block 3 pillows.
This one took me a while to figure out. Basically, you need to hold W (or whatever you have as the up button) whenever the 2nd kid throws a pillow, and it'll go right by you. Do this 3 times and finish.

I'll also add this tag to make this video easier to find:
