Later, Shira and Diego went to Manny and Ellie's anniversary party. They ate some berries and talked about having their own kids. However, Shira was reluctant because kids are afraid of them. A Young Start and Young Aardvark stumbled upon Diego and Shira and saw the berry juice dripping down their chin. The sabers acted friendly, but thinking the juice was blood, the kids ran away in fright. Shira was puzzled and told Diego that she even smiled. Later, there was a meteor shower and an asteroid approaching. They hid in an Ice Cave until they thought it was safe.
An old friend of the herd, a weasel named Buck, came back from the Underground Dinosaur World. The weasel greeted Shira who couldn't believe he was a dinosaur whisperer, and began salsa dancing with her. Buck then offered to let the saber count his teeth, which she declined disgusted. The herd learns from Buck that the meteor shower from last night was just the beginning and an even bigger asteroid is approaching. Luckily, he tells them that he has a plan to save the planet and asks the herd if they're in. Diego assures Shira that Buck has saved their lives before, but she still worries if he can this time. Convinced, the herd gets to move on.
Along the journey, the herd comes to a river. Buck comically commands it to let them pass which Shira and Diego express their doubt. Suddenly a moon passes over and gravitationally pulls the water causing a path to open up. The sabers dropped their mouths in surprise.
After crossing the river, the herd is led through a forest where an electrical storm hit. Shira stopped when she noticed her fur by her paw becoming fuzzy from the static.

Shira is amused when Diego points out that Granny does too.
After the Llama refused to help them the herd decided to spend their seemingly final moments exploring Geotopia. Shira and Diego are seen snuggling gently as they watched the crystals. After Sid broke the Geotopian wall, the Geotopians agreed to give up their crystals to save their lives. The crystals were put in a volcano, to move the asteroid elsewhere. The plan worked and they celebrated their victory.

Buck brought an idea to stop the tornado and to find the place that could find a clue to stop it is on the site of the impact of the previous ones. So Shira and her friends accepted it.
