scalar $bears is correct if you want a reference, which is how you were
using it before.
to say $bears->{food} is correct if that's what you want.
If instead you just want a normal hash, change $bears to %bears, but
you must also change the {} around the contents to (), and the
references like $bears->{food} to $bears{food}

Do you want to know how many keys there are?
try
scalar keys %bears

If you're using the reference syntax, dereference it in the loop
structure.
for my $key ( sort keys %{$bears} ) { # . . .
