From Pikipedia, the Pikmin wiki
The Dream Material (ドリーム・マテリアル?, lit.: "Dream Material") is a treasure in Pikmin 2. it is a large, greatly used white eraser. It is found on the last sublevel (6) of the Glutton's Kitchen, and is held by the territorial Giant Breadbug. When this treasure is retrieved, the ship turns it into a usable item known as the Anti-Electrifier. If the Giant Breadbug is defeated first, the other Breadbugs won't take the Dream Material to their dens. Like some other treasures, if the player defeats the Giant Breadbug, but does not have enough Pikmin to carry the Dream Material, which requires the strength of 10 Pikmin, it will change weight to match the player's army.
“This is yet another object I've recently discovered that is beyond my wildest dreams. It doesn't conduct electricity, but it can erase marks left by pencils with remarkable ease. Sadly, the more you use it, the more it rubs away into oblivion. Hmmm... In a way, it reminds me of my job...”
“This nonconductive substance has many uses: I have discovered it can even erase pencil marks. It is a dream material! But the more it is used, the more it crumbles. The same is true of dreams.”
“Processing...How bizarre. An item appears to have fallen out of that freakish creature.
It must have been a greedy beast to swallow something like this.
This intriguing material does not conduct electricity.
It is far more advanced than the material I was researching. ...How frustrating.
A space suit made from this wonder alloy would insulate the wearer from electric shocks.
Excellent! This new material has allowed me to complete my Anti-Electrifier!
It is my own invention, with only the smallest iota of outside inspiration.I have reconfigured your suits with this new material. They will now protect you from electricity!”
