Ichy and Dil

"Thanks for inviting us...to dinner!"

- Ichy

Ichy and Dil were the main villains of The Land Before Time 4: Journey Through the Mists. Their main goal in the film was to eat Littlefoot and his friends.

Ichy is an annoying light blue Ichthyornis (called a sharpbeak). Dil is a nearly blind, teal green Deinosuchus (called a big-mouthed bellydragger). They work as partners to catch their food to set aside their disadvantages. Ichy calls himself "the eyes" because he guides Dil and tells her where to go, and relies on Dil because he is too small to catch his own food. Dil calls herself "the teeth", but despite her size she has bad vision and needs Ichy to guide her. The two constantly argue about who is better and say that they don't need each other.

The two are first seen inside a cave trying to eat Littlefoot, who was hiding in crevices. Just when they were about to eat him, his friends came to the rescue by pushing rocks at them. Ichy and Dil follow the gang to a river, and Dil tries to capture Cera when she is falls into the water. Luckily, Ali dodges Ichy's attack and rides a confused Dil to rescue Cera and get to safety. Later, Ichy and Dil arrive a third time and chase their victims to a log over a ravine. Ichy captures Ducky, though Petrie tries to save her, only for Ducky to fall. Ducky is woken up by Spike and manages to grab a branch just when she was about to fall into Dil's mouth. Spike then pushes Ichy off the edge, where he almost gets eaten by Dil.

After another arguement, the two decided they have finally had enough of each other and split up. Ichy is hit with Dil's tail and flung into the distance. Shortly after, Dil encounters a hungry elasmosaurus and calls for Ichy as it chases her. Their fate remains unknown, as neither of them have been seen since.
