[LaLaLand]

I remember having it on VHS as a child (early 90's) and used to love it but can't for the life of me remember the name of it.

It was American and was something like "[Name] & the ________" and it was something about a diamond, or a ruby/gem.

Anyway, the protagonist (glasses and red hair) goes looking around what I remember being a jungle and finds a temple and goes insideetc etc.

There's also a female animal hunter/poacher who's in the jungle in like a camper van thing with caged animals.

At the very end the protagonist traps the poacher in a rope and cages her before she turns "nice" and he lets her go along with her animals.

It was like a similar 'style' (appearance) animation to like Thundercats and that, not comical or anything.

I know that's all a bit here and there but I'd be grateful if anyone knew of it, I'm trying to find it for my little cousin to watch because I loved it and I'm sure he would too.
