Kaktos is one of the Plant Kingdom horses
He can be watered instead of drinking.
Their skills increase when you give them Droppings within the limits set by the total skills of the best horse in the game. The skills increase depends on the amount of Droppings the horse is given, as well as the season in the game.
When he reaches 2000 skill points, he can be pruned. His skills will then be reset to 0, but he'll give you 1 x unicorn foal of a breed you don't have yet!
This horse cannot be sold.
