One possible fanfiction idea could be that Shira discovers she is pregnant during the chaos of the events in 'Ice Age: Collision Course'. She could be initially worried about how Manny and the others will react, but as the story progresses, they all come together to support her. Maybe she has some special cravings that lead to comical situations within the group.
The plot could be centered around Shira trying to keep up with the group's adventures while being pregnant.

But her pregnancy also gives the group a new sense of purpose - to protect her and the unborn baby.
A fanfic could focus on the relationship between Diego and Shira. Maybe Diego wants to show Shira a special place he found in the Ice Age wilderness.

And at the end of the journey, their bond grows even stronger.

One possible scenario in a Diego and Shira love fanfiction could be that they start off as rivals in the ice age world.

They might share secret glances and small acts of kindness that slowly build into a deep love.
