Sesamin Ruins (セサ民遺跡 Sesa-min iseki) is the second stage in Glucosamine Desert.
3 St. Pigge the 2nd's appear all at once as the main threat once the base is hit.
Using anti-reds is highly recommended along with ranged cats as support. Like many of the earlier stages in SoL, Farmer Cat in the very beginning can help defeat the peons and give you extra money. Bunny and Canard at Lv. 7 can take out the St. Pigge in two hits.
