T. rex in Dinolets
T. rex is egg number 1 of 12. In the game it's green, and its special feature is the one the voice calls out: "Big sharp teeth!" The voice says its name as "tee rex".
In Feed it eats meat, and from level 2 your child is asked to pick the right food for it. Once it has hatched, it joins in the other games too.
