During your adventures in Dinoland, you will meet many characters. Some of these characters, like Grandpa Joe will set you various Missions.
Each Mission has a particular objective:
Your Dinoz can only accept one mission at a time, so choose each mission carefully. Once you have completed the mission, your Dinoz must travel back to the character who set the mission in order to receive your reward.
Certain missions are locked at the beginning of the game. In order to unlock them you must first complete the missions which are set, increase your Dinoz' level, or complete certain Quests set by other characters in the game.
Once a mission has been completed by a Dinoz, you can do it again with another Dinoz.
