Can't get back into aqua base. Need murkrow!

[Jhawkin7]

I'm about to fight solaris for the 1st time and id like to not just get swept. But I cant get into team aquas base for the murkrow, is there a side quest I can knock out before fighting solaris or am I just gonna have to find a yamask?

If you joined the Aqua Gang, you can simply catch it.

 

If you joined the Magma Gang you need to first do the raid on Craudburry's house(above the bike shop if I recall correctly), and then do the raid on Aqua Gang's alley.
