I would appreciate any help you can offer. I'm on level 4-4, with the ceiling blocks that fall right after throwing the 1-2-3 balls into the slots. I've searched and searched, and all the walkthrus say "use Baby Mario and run fast." But I get squished every time! I've tried Baby DK and the dash feature, and still get squished. Is there a secret to this level that I'm just missing? I've burned through 15 lives trying to figure this out, and I'm stumped. Please help a fellow gamer!

I was stuck at this part on the level to, but I know how to get further: When u hold the eating button ( B or Y) when mario is on ure back. yoshi's sprints. so u just do that and u will make it

if u r trying to get the no. 2 ball then use dk to swing on the ropes and then go through the door. get mario and go and to the end. hold Y and run to the end. then use dk, go through the door and swing across the ropes. i had trouble with ball 3. but if u need any help on the other balls just ask me.
