Problematic Cows

Enter Lord Jabu-Jabu and in the very first room stand on the floor(not the angled slope) in front of one of the cows in the wall.Play Epona's Song.The cow will offer Link some milk, but after it stops talking you'll get no milk. The cow is now "stuck", it doesn't moo and can't be interacted with. If you walk up the sloped ground in front of the cow to get closer to it Link will recieve a bottle of milk and the cow will revert to normal.
