Animorphs Megamorphs: In the Time of the Dinosaurs

In this story, the Animorphs (Jake, Marco, Tobias, Cassie and Rachel) go on a mission to find a lost army sub.
But a nuke from the sub goes off, starting a "Sario Rip" or in other words they travel in time.....to the time of the dinosaurs!  Will they be able to make it?  Or will they be lunch for a T-Rex?  I liked this story because it was funny and adventurous.

Animorphs Megamorphs #4: Back to Before

In this story, the Drode comes to Jake and tells him that he can go back in time to before they met Elfangor.  The problem is that Jake must decide now.  If he changes everything, they may not have their morphing powers.  I liked this story because it was not short, but it was long.  I also liked it because it was serious.

Animorphs Megamorphs: Elfangor's Secret

In this story, Visser Four has found the Time Matrix.  It could cause trouble, so the Animorphs are trying to stop him.  My least favorite part was when somebody shot a bullet in Jake's head.  My favorite part was when he was still alive in the end.
