Ryshu runs the Mystery Island Training School, where you can increase your pet's statuses (Strength, Endurance, Defence, Ability and Level).
Courses[]
| Course Type | Neopet Level | Cost | Length |
| Grasshopper | 20 and Under | 1 tan codestone | 2 hours |
| Basic | 21-40 | 2 tan codestones | 3 hours |
| Intermediate | 41-80 | 3 tan codestones | 4 hours |
| Adept | 81-100 | 4 tan codestones | 6 hours |
| Advanced | 101-120 | 5 tan codestones | 8 hours |
| Expert | 121-150 | 6 tan codestones | 12 hours |
| Master | 151-200 | 7 tan codestones | 18 hours |
| Grand Master | 201-250 | 8 tan codestones | 24 hours |
After level 250, you will have to continue your training at the Secret Ninja Training School, which is also located on Mystery Island.
Note: Your agility, strength and defense can only be trained if all your stats are equal to or less than twice your level. Endurance, however, can be trained if your stats are equal to or less than thrice your level. (Ex: If your pet is level 50, with strength 75, and endurance 120, and you wish to train in strength, you will need to get your level up to half of your endurance, which in this case would be 60 (120 / 2 = 60))
Lessons are paid with tan codestones (Mau, Lu, Vo, Tai-Kai, Eo, Main, Zei, Orn, Har, Bri), which can either be bought via the Marketplace, Trading Post, and Auctions or be found in random events around the site.
