I learned that Scratte was also in Ice Age 4: Continental Drift, not just Ice Age 3: Dawn of the Dinosaurs.

First, she was seen as Siren's disguise, then she was seen as many residents of Scratlantis.

Karen Disher was credited for voicing Scratte in Ice Age 4 and part of the Ice Age 4 voice cast.

I've got 139 signatures so far and now 61 signatures remain on this petition, so keep on sharing to make Karen Disher reprise her role as Scratte.
