If only things were so easy for Marvin. He’s travelled for like miles and there stands a cluster of rocks and blocks on his way and he needs to put them away and he’s just as lazy as you and me.

Marvin is pleading you to make him a traveller robot which trails through rugged terrains, sandy soils, mud pools, water tubs carrying building blocks for constructing a stockpile.
