I loved this movie when I was younger and I just can't remember what it was called.
I'll try and describe it;

In the begginning these little forest animals go on a field trip into the forest and then humans come and spray poison in the forest where the animals are. I think one was a mole.

The animals have to go on a long journey to find a healing flower for their friend who was badly hurt by the poison. They start off in a little flying machine and crash.

In another scene the animals are attacked by an eagle and taken into his nest.
Another scene is in a construction site where they get into more trouble with the equipment.

PLEASE if you know what this movie is called, I'd really appreciate it. Its been bugging me for weeks.
