It was speculated that some dinosaurs may have had two hearts to help pump their blood around. Earth worms supposedly have six hearts.
Fish are the animal group that have two-chambered hearts. Reptiles and amphibians have three-chambered hearts and mammals have four-chambered hearts.
NONe there is no two heart animal ........ DNG AKA DeathNoteGal
Chickens just like most any other animal have only 1 heart.
A worm actually has seven hearts, i don't know why but it does. Example: If you chop up a worm into 7 pieces it will still be living because there is likely to be a heart in each section. DOes this help and it is all i know????
You cannot buy it from Horn Farm (but you might be able to get it in the animal festival?) so you need to have a sheep with 5-10 hearts. if you have 3 hearts though you can still get it but its uncommon. if you have 0-2.5 hearts then you will never get it. I was really annoyed when I got to this part of the game because I had just sold my sheep with 7 hearts so I had to get another and earn the hearts all over again!
