The D-Team is searching for the third Cosmos Stone when they encounter Sheer, who is also looking for the Cosmos Stone. Sheer summons Mapusaurus to attack the woodcutters that disturb her sleep, and then ends up attacking the village. Rex summons Ace to attack Mapusaurus but Mapusaurus uses Heat Eruption, causing a volcano to erupt with flaming meteors forcing the two groups to retreat for a little while.
Sheer once again summons Mapusaurus and Max summons Chomp, using Gatling Spark to defeat Mapusaurus. The D-Team's dinosaurs use Lightning Strike, Biting Wind and Emerald Garden to stop the lava from the volcano.
Sheer vs. RexEdit
When Mapusaurus uses Heat Eruption , a real volcanic eruption ensues, forcing both sides to retreat.
Sheer vs. D-TeamEdit
Once again, Sheer summons Mapusaurus to fight the D-Team's dinosaurs. When she grabs the monk, Paris uses her call to force Sheer to drop him.
- While Sheer is complaining to the D-Team and flipping her hair, the dark purple trim on her lower skirt vanished.
