28

Spectre and Brontikens have joined the battle. When Brontikens' Spectral Destroyer hits a volcano, its eruption causes the Space Pirates members to withdraw their dinosaurs. The D-Team also withdraw their dinosaurs and retreat onto the timeship. Dr. Z and the Alpha Gang are rescued by Helga as the Black Cosmos Stone falls into a Woolly Mammoth's mouth. When the D-Team learn about this, they head to the part in time where Dr. Spike Taylor and a younger Max uncovers this. After an earthquake drives the younger Max and Spike Taylor away, the D-Team and the Alpha Gang begin excavation when the Space Pirates arrives. When the D-Team and the Alpha Gang are beamed back aboard the timeship, Dr. Z revealed that he grabbed the Black Cosmos Stone and the mammoth fossil at the last minute. The Space Pirates end up giving the D-Team their parents only for them to turn out to be Gel Jarks in disguise which capture the D-Team. However, the Black Cosmos Stone turns out to be a fake as well and Seth communicates with the timeship to give up the Black Cosmos Stone. Seeing what Seth is up to, Spectre orders his minions to stop him. When Gavro unleashes Gigas, Seth unleashes a Cryolophosaurus. Foolscap and Sheer also unleash Armatus and Maximus. On the timeship, Helga discovers that the Gel Jarks can't stand salt when she punches two of them. Seth uses Blizzard Smash to freeze Gigas, Armatus, and Maximus. Seth then commandeers the timeship to escape and obtains the Black Cosmos Stone. Helga uses salt upon the Gel Jarks holding the D-Team and the Alpha Gang hostage freeing the D-Team and the Alpha Gang who fight back. Max and Chomp confront Seth and the Cryolophosaurus.
