Compared to the big production houses, the cgi animation many not be quite as polished, but the background scenery is very well done.
From my first impression, the animation appears to be dubbed into English - Not "out of sync." as the other reviewers stated.
This is confirmed when looking at all the opening and closing credits - which are in Español - so I would be quite certain the original audio for the animation was Spanish ... NOT English !
* IMDB - whomever posted the original info here is incorrect stating USA origin ! - the Origin should be South America *
Today nearly everyone should be used to watching "dubbed" animations as there are so many cartoons originating from Asia (anime) and elsewhere which are mostly subtitled or dubbed into English - since at least the early 1960s .
... all that aside, they are trying to tell a story about an invading "monster" a mechanical logging machine which was destroying the rain forest ...
I will leave it that, and will suggest you take a look at this Jungle Tales film then make your own opinions ... it definitely is not that bad.
