The first, main, small and most common base in the Plastic World (but not the best and bigger)

Called “Green Base 001”, this base became notorious when it was the center scene of the first events of Sarge’s Heroes, when the Tan Army unexpectedly attacked the base, no one noticed. Same place where Grimm office is.

Having been taken by the Tan Army, after Plastro obtained what he was looking for, it was left behind with a minimal garrison, which was no match for the Green troops who retook it.

Some time later, Grimm discovered a portal that leads directly into the Green Army Camp. The Tan Army have been using this as a means of attack the Base location, and they needed to be stopped. Sarge manages to get back home where he has to defend an invasion of the Green Army Base from the Tans, closing the Portal once and for all.
