You know how when you buy expensive medical equipment or exotic African fruits or a handgun with attachable laser targeting and a modified clip allowing for 22 rounds, they come in Pelican cases with custom foam inserts? Or maybe you don’t know.
Either way, do you think they could modify a large foam insert to fit a human snuggly into a small compartment? Not even a large human. Say a human the size of a Boston Terrier. And the compartment would be roughly the size of a crib. And while the case would need to be soundproof it would allow a free flow of air. Because seriously, enough of the crying already.
