In an attempt to get Jimmy Valmer and the rest of the Blue Team killed by the Tardicaca Indians, Nathan hatches a plan to replace Jimmy's map to the scavenger hunt with a map to the Indians' reservation. He tells Mimsy to switch the maps, but he ends up screwing up the plan and Nathan ends up with the map to the reservation. The Indians then show on on horseback and attack Nathan by shooting him with arrows. Towards the end of the episode, the Indians show up again to shoot more arrows at Nathan after his plan to kill Jimmy with a ukulele solo backfires on him.
Most of the Tardicaca Indians wear feathered headbands on their heads while some are seen wearing vests and pants made of animal fur.
