Chunky friend (or friend Chunky) let out a noise that was not quite snicker or giggle, or perhaps even laugh.
But they couldn't compromise the rapport they'd just built - and perhaps secured! - As they traveled deeper into the growling guts of Draco. Despite the convenient meat shield, Snicker found themselves trying to peek from behind Chunky's fat legs, something prickling across their spine no matter how safe they thought they were.
An incidental glance back, to check how far they'd wandered from the tunnel, netted an unexpected result.
