Quest Guide
The Strange Yumkasaurus seems to be blocking the path, but no one knows why. You need to communicate with it. First, transform into the Yumkasaurus behind you. Then, find out it's just hungry. Give it some food (raw meat is recommended). After it eats, it falls asleep. Now, you need to wake it up. Transforming into it won't work. Go with your Tepetlisaurus friend and look for a treasure in a little tunnel on the left. There's only a note inside the chest. The Strange Yumkasaurus' master was testing empathy. After talking to the chief of Scions of the Canopy, Wayna, he'll arrange for someone to feed the Strange Yumkasaurus daily and rejects the previous master's actions. You'll get 20 Primogems and 26,500 Mora.
Secret Achievement
At the end of the quest, transform into the Yumkasaurus again and feed it raw meat to get the "A Final Kindness" achievement worth 5 Primogems.
