Maniac Mansion Deluxe Problem

[newbie_82]

I won this game with Michael and Wendy but Michael is the only one who can open the grating at the porch.  Now I am playing it with Razor and Bernard and none of them can open the grating.  As well none of them can open the garage.  I get the message I can't budge it or it's rusted shut.

Take your characters up to the top floor, and use Hunk-O-Matic (body building) machine a few times.  Then they are strong enough to open the grate.
