Pros-
Her belly will obviously be the major (and greatest) part of the hug, as it is big and soft (as in one of the softest parts of her body).
Tonash is a gentle giant, so she'll try not to crush you.
She'll most likely add in a snuggle or two.

Cons-
Her curves are both fat and very muscular.
There's a chance she'll hug a bit too hard and forget that humans and other species aren't nearly as hard to squeeze as Golioums are.

The big question is...
WILL YOU HUG HER?
WILL YOU SURVIVE THE HUG?
WILL YOU DIE FROM THE HUG?
WILL GOKU EVER FIND HIS SON?
