Enchanted Apple

It was a perfectly normal day of camping with Dave and Tristan, when Tristan is suddenly missing. Dave just told him to explore for a little bit while he was setting up, but he didn't know he would wander into the forest. Anyhow, he shouldn't be too far. It's not like he was transported somewhere by some magical fruit.. Right?
