Spiders (unofficial name) are found in the Watch Tower. They have the ability to climb walls and fly around. When flying, they can attack Tomba from above.
When struck by any weapon, it will be flipped on its back. In this state, Tomba will take damage from its sharp legs during contact. If the spider is hit twice, it will be flipped on its feet and become stunned for a few seconds. If the spider is struck for the third time, it will be defeated but won't award the player with any Adventure Points.
