[Eggman does indeed move about as he monologues, in fact, he's stomping along the ground to pick up the Triforce Shard lying on the ground.]

The obvious plan is to gather all three shards together. According to lore, the Triforce requires three individuals that personify the ideals of power, wisdom and courage in order to be reassembled and properly function. However, I believe that if I can study the Shards, I can create a machine that will simulate this function and allow it to be properly usable!

...That is, provided, you do have the other two Shards.
