Sid reaching under the bison

After the Baby Dinos hatch, and they bite Sid, they start crying, and Sid thinks they are hungry. He goes to a sleeping bison, and tries to get some milk for the Baby Dinos. However, the bison turns out to be male, and Sid runs away, shouting, "I thought you were a female!" The Baby Dinos follow, with one of them carrying the fragment of egg shell Sid had brought to use a plate.
