How do you kill the ninja bear?

In Triple Town, there is a bear who looks somewhat like it's dressed up as a ninja. It jumps from open space to open space on each turn. Is there a way to trap the bear to kill it like the other bears, or any other way to get rid of it?


Solution 1:

According to everything I have read (because I was wondering the same thing), the only way to kill ninja bears is to use an Imperial Bot on them.

Solution 2:

You can also kill it by filling every other space.
