Performing the technique in
SSB (abbreviated "
ECE") is a
technique performed by
Yoshi that is performed by releasing from the
edge, by pressing down or away from the edge, double jumping and then launching an
egg. This must be done fast enough so that when done, you do not land on the
stage or too far above the edge. After the egg is thrown you can grab onto the edge, canceling all
lag and renewing your edge
invincibility frames.
[edit] Reverse Edge-Canceled Eggs
Reverse Edge-Canceled Eggs (abbreviated "RECE")is a technique similar to ECE. Reverse Edge-Canceled Eggs are performed in generally the same way, but instead of launching your eggs towards the stage, you launch outwards. This is done by quickly turning around with your second jump. This is a more risky alternative because if missed, Yoshi will plummet to his death.
The technique can be performed in
Brawl.
