It turns out instead of a TV series like it was initially reported, it's going to be a series of films for Disney+.
We have learned that Disney/Fox are in early development on spinoffs for the ‘Ice Age’ and ‘Rio’ franchises. Blue Sky Studios is currently set to be the production company behind these spinoffs. Per sources, we have been told that the ‘Rio’ spinoff will focus on Nico and Pedro and that the ‘Ice Age’ spinoff will focus on Buck. It is currently unknown at this time if the actors that voiced these respective roles will be offered to reprise them for these spinoffs given how the spinoffs are in early development.
