Emperor Amprat

Once you open up the fridge, the Emperor Amprat will chase you all over the ground floor of the dungeon, trampling any Pikmin underneath it. it can also cause static electricity with its whispers.

Piklopedia Entry
''The king of the Amprats, the Emperor Amprat is highly territorial. It is ravenous most of the time, and often found with food not too far away.''

Strategy
For the first portion of the fight, the first thing you must do is get to higher ground above the Emperor Amprat. The Emperor Amprat moves much faster than you and your Pikmin, but it can't turn too well in a full sprint, so a run to the side can avoid tragedy. Once you're above the Emperor Amprat, throw down your Pikmin from above. You'll have to go back down if you wish to save any of your Pikmin, as they'll be stuck on ground level once shaken off.

At 50% health, the Emperor Amprat will begin using electricity against you, and an electrical charge will cover its body as it charges you. There's a number of heavy items that can be moved off the edge of the higher ground, so you'll have to get the Amprat underneath it first before pushing the item off the edge, making the Emperor Amprat remove the electricity and open to attack. Continue this strategy until it falls in defeat.
