oh PLEAAASEEEE
It is just a visual pun. The reason that they chose a beaver is that they couldn't anthropomorphize a "Va-jay-jay" or a "Hoo haa."
Honestly, I am with the other posters and find it charming that they frame menstruation in terms of having a positive-friendly relationship with your nethers. Beats the hell out of all the products the sell to perfume, prune, and freshen.
