The word 'shelly' originates from the Old English 'scealu' (meaning shell) and the diminutive suffix '-y' (meaning small or little). Thus, 'shelly' refers to something that is small and resembles a shell or is covered with shells.
Think of something that is 'small' ('-y') and resembles a 'shell' ('scealu') — that's why 'shelly' describes something that has a shell-like quality.
