Does anyone know the name of this film where these woodland animals (incl. a badger, mole and hedgehog I think) set of to find this flower that will save a younger relative? At the start their parents get captured by some people that I think are actually helping the animals because they gas the forest... Thanks!

It's Once Upon A Forest : )

I'm not sure if you got your answer yet but it sounds like fern gully:p

Its once upon a forrest my daughter loves this movie and makes me watch it over and over
