A little boy called Mampato uses his time-travel belt to visit caveman Ogu (apparently a pal from previous adventures) and the pair head to Rapa Nui (aka Easter Island) to find out how the big stone heads were made. They enjoy feasts, learn about ancestor worship, and get caught up in local power struggles. The talky script makes for a lot of reading for non-Spanish speakers, and its educational agenda gets lost in thickets of local terminology—I was struggling to keep straight the differences between mana, manutura, tangatu manu, moai, etc. The animation is a bit rough and jerky. Alejandro Rojas directed (2002). In Spanish with subtitles. 78 min.
