Taiyou no Ko Esteban

Synopsis

The children set out to find Puna, Zia's home village, but to get there, they must go through a pass blocked by Pizarro's fortress which is built atop an underground temple. Sneaking into the temple, the children find an old priest named Pasha who helps guide them further, but Pizarro sets a trap for them. Pasha reveals a secret escape route through a puzzle room, which once solved, melts a pillar of ice that collapses the temple and likewise brings down Pizarro's fortress. During the collapse, the children become separated from Mendoza and his men.
