This is a very weak enemy, intended for rewards stages. In fact, you could make a good case for this being one of the the weakest enemies in the entire game, not only for its HP, but for its attack power, attack speed and the lack of movement. Take note that this is a Metal enemy.

Package Doge, Angry Sun and Drummer Doge are the only stationary enemies in the game, due to the lack of movement speed.
This enemy is actually a reference to the company Amazon, not only in terms of how they deliver their parcels usually with excessively large boxes, but the enemy actually has the word "wamazon" on the side of it.
