I would let you, but only as a lawful good peace cleric

Have you considered 3 giant miniature space-terrasques in a trenchcoat? The were 3 wild terrasques minding their own business in the wild, when they stumbles on a druid orgy who were all tripping on shrooms. They magically shrunk the terrasque family not realizing that their int was inversely proportional to their body size. Now the clever tiny devils are on a quest to reverse their shinkification. Without their enourmous size they must rely on their wits to survive in a land of humanoids. The only tools at their disposal are 3 pairs of women's undies and a trenchcoat.

1st the clever crew must find the rare Psilocybe semilanceata, the mushroom that powers the druid magic. Then they must find the elucive druid and his circle. Finally they must recreate the original conditions by seducing an entire druid circle into an orgy without being discovered.
