The Smoky Progg is a hidden boss in the first Pikmin game, and is possibly one of the toughest. The only way to encounter it is to go into The Distant Spring area before day 15. It resides in the massive lake area, on a later useless mound of small islands,(which, interestingly enough, appears to be an imprint in the ground left by a plastic bottle).The Progg resides in an egg and if you touch the egg by any means, even with Olimar, it will break out. The Progg, (when released from the egg), is dark green and black creature, that sports glowing white eyes. The Progg also emits gases that are poisons to Pikmin. It can also uproot Pikmin sprouts. The Smoky Progg will follow you back to the landing site, so it's necessary to kill it. It has an incredibly high defense, and takes a while to kill.
However, when killed it drops a pearl or nut that will be sufficient food to produce 100 Pikmin from any Onion that it gets to. Olimar's belief that it is a malformed Mamuta larva is most likely based upon the fact that both creatures effect Pikmin on a different end of the same spectrum; the Mamuta plants the Pikmin, (which enables them to become flower Pikmin), while the Progg uproots Pikmin and thereafter kills them. They are also synonymous by name; "Mamuta" can be translated as the God of Pikmin, whereas "Progg" as the Lord of Pikmin.

Stratagies to Defeat the Smoky Progg

Large masses of pikmin are not recommended to fight it; it is best to use a small number of reds, wait until it uses the uprooting move, and then throw the reds onto its face. After the reds are shaken off, repeat the process. The only way to hurt it is to throw Pikmin onto its large head. Any Pikmin left walking in its trail will succumb to the poison.

Egg Glitch

In a rare case, if you walk up to the egg as Olimar with no Pikmin, circle the egg and press A to try to attack it, the egg won't take any damage, yet if you go back to an onion to get your blue Pikmin and return to the cluster of islands, the egg will be gone. The only way to reset the egg is to reset your game. Going to sunset and continuing to the next day will not bring the egg back.

Olimar's Notes

I believe this creature may be a malformed Mamuta larva.
