That one egg thing Yoshi players do on the ledge

[TravisRoland]

How do they do it? I am referring the when they grab the ledge. Let go. Throw an egg. Grab the ledge again. Every time I try it I SD :\ and in case it matter, I play with tap jump off

Press back on the ledge to let go, jump and then throw an egg in quick succession. As you'd know, the egg toss will cancel out your double jump so be careful as it's really easy to SD with it, or just the same get knocked out of your jump then bam you're dead :/
Just make sure you throw the egg above the ledge a bit so you can still re-grab it.

Thank you. Just gotta head into the lab and practice this. Practice makes perfect

This is one of Yoshi's hardest techniques to master in my opinion. The most effective way I found to practice it is to go to Temple on training mode and practice on the edge in the very top middle of the stage. Every time you fall you can just lightly down B and re-grab to go again without wasting time coming back from the stage. Just like playing an instrument, start VERY SLOWLY and after much muscle memory and repetition, speed up a little, rinse and repeat.

Just requires alot of patience and practice.
