Ninja Construction

The NInja Construction is an event going on at the Ninja Hideout. It is probably a path to a new room which may be the Tallest Mountain. However, ninjas are confused about that because they don't know what is going to be the new thing. It may be a new ninja-only room for extra cards.

Trivia

 * Many penguins may think that Sensei's favorite element is fire, as you have to find fire all over the island.
