When Sid lets the Baby Dinos into the playground, everyone else goes in as well, and the Baby Dinos cause a lot of trouble. There is one instance where Sid tries to get a baby dino to spit out baby Johnny, but first he spits out Madison, a baby Terror Bird. The mother Terror Bird takes Madison away.
Just after, when Momma Dino attacks, the adult shouts "Earthquake!" (thinking Momma Dino's footsteps were an earthquake), and buries its head in the ground. Madison tries to copy her mother, but knocks herself out in the process.
