Sam & Max: The Devil's Playhouse - Episode 4: Beyond the Alley of the Dolls

Being beset by a horde of Sam clones following the end of They Stole Max's Brain!, Sam & Max lose The Devil's Toybox and flee into Stinky's Diner along with General Skun-ka'pe. They find the secret escape tunnel they used before isn't working, but after acquiring the mind-reading Toy of Power Skun-ka'pe had been holding onto, they discover another secret escape tunnel. This tunnel leads to a highly-advanced room filled with cloning equipment apparently used to create the clones. Since this equipment is made by BoscoTech, suspicion falls on Momma Bosco. After successfully returning her to their plane of existence via a seance, Sam & Max eventually find out that she's not behind the clones herself, but did make the cloning equipment for some unknown customer for a large amount of money. Luckily she should be able to take command of the clones, if she can get a new body.
