Seriously, just assume that NOTHING you do while Sonic is HA'ing under the stage (minus hitting him) will make him stop. You can't do anything about it except going to hit him.
IDK who asked this a while back, but it's pretty easy to initiate a HA stall while preserving Sonic's second jump.

Last page you said you doubt Ganon could hit Sonic without putting himself in a terrible position. The same thing goes for Ganon approaching a planking MK. He can jump off and try to stop it, but good luck to him. He'll need it.
