The big spotted goat pile doesn't do anything. Sorry, it's just there for decoration! :)
It is under the pile of leaves.
No, pile is a verb and a noun. verb: The nets were loosely piled on the Vancouver Island pier. noun: Take care not to trip over the pile of nets.
It is in a junk pile inside Sully's (to the left).
Yes, they will eat goat heads (puncturevine). Especially if you pick the goat heads, put them in a pile to dry, and then let the goats at them once fully dried out. I had a pile like this that sat for two weeks and brought goats in and it was one of the first things they ate, seeds and all. If still green, they will eat the leafy parts of the living plant and spare the seeds and most of the stem, but if dry they'll eat it all!
Snoopy wafts them left and into the pile by blowing them, one by one. Point and click to blow, and carry 5 leaves to finish the game.
You get him to organize the leaves in a pile, by blowing on them as they fall. Start at the right, and when one drifts down, click to blow underneath it to steer it left, onto the pile.
The large pile of stones known as Snaggletooth Rock is at Puerto Rico, at the center star of the driving map for the jeep. You can't really do anything there on your first visit, when you get the fur from the brother's fence and the bolt cutters from the upper left star. But after you check the DNA on the fur at Mews' lab, return to Puerto Rico to help the herder catch the chupacabra.
After Snoopy blows the leaves into the pile, Linus will jump into it.
You follow him when he leaves and he will tell you his blanket is missing. Go back to the pile of leaves and look for it. After that, bring it back to him.
The scene immediately after Linus gives you the invitation is Charlie Brown and Snoopy in the back yard (left). Snoopy blows some leaves into the pile as they fall, then Linus jumps on the pile. Follow him to the mailbox, then return to get his blanket from the pile.
Follow Linus to the right, but when he reaches the mailbox, he realizes he is missing his blanket. Go back to the pile and sweep your mouse over the leaves to uncover it, and bring it to him.
On the Snoopy mini-game, he will sometimes blow the leaves over the pile if they go too high. When it gets close, don't blow any more.
