Mechagon: Scrappy's Best Friend

Around Rustbolt in Mechagon you will sometimes see a small robot dog collapsed on the ground.  This is Scrappy and there is an achievement relating to him,
Scrappy's Best Friend - Revive Scrappy in Rustbolt and feed him a Mechano-Treat.

The Mechano-Treat is a tasty treat that small robots might enjoy and can be made by Pascal-K1N6 once you have uploaded the blueprint into his database.  This blueprint I got from Bonepicker, but it also drops from The Scrap King, Ol' Big Tusk and Gorged Gear-Cruncher.  It costs 100 spare parts to make 5 treats which are soulbound so you unfortunately cannot buy or sell them on the auction house.  There are no comments about these having any effect on other pets and I tried feeding them to some of my mechanical battle pets but it just said invalid target.

To complete the achievement Scrappy's Best Friend you need to find Scrappy, collapsed on the floor around Rustbolt.

Use 1 Energy Cell to revive Scrappy who will jump up, bark happily and nuzzle your leg.  Then feed him a Mechano-Treat and you will get the achievement.
