The first unit available through the Ninja Tech.
Ninja bombs are used to break walls to make an entrance. You might want to have >5 Ninja Bombs. Be careful, though. They have very low health so you might need to use a samurai to attract demon mortars and dragon cannons. The samurai won't attack much, it is just to protect the ninja bombs.
