Cherrygrove is a smaller city. Besides the beach there wasn’t too much of interest there.
[He did like it at Cherrygrove but Eagle is used bigger cities than that where there are more things going on. ]
An HM is a move that you can teach Pokemon. It is kind of like a TM but HMs can be used more than once and they can help in journeys in Johto. For instance HM Fly is supposed to teach your Pokemon how to carry their trainer through the air to other cities. That would cut travel time down a lot.
