I understood the Clancy's word for snails as "shell-a-kie (?spelling)Boogies" I wondered if this name related to the type of mischievous, sometimes dangerous, supernatural beings called variously bogies, boogles, bug-a-boos, bogeys. - snails being a shelled variety - but I've never been able to confirm this. My Irish frieds just said they called them snails.
