Every stallion, colt and dragon must survive mares in heat. 1 Dragon, 8 stallions, 5 colts against 30 mares, 7 fillies, will they survive.

P.S. Since the 5 character maximum i cant tag them all so here are the survivors:

Spike, Soarin, Fancy Pants, Big McIntosh, Braeburn, Snips, Snails, Pipsqueak, Featherweight, Caramel, Dr.Whooves, Thunderlane, Rumble, Noteworthy and an OC Character by the name Arty.
