Mollusk

The doorbell rang yesterday and I opened to find Neighbour wanting to hand me a bag of mollusks.

He asked if we eat them but I only stared blankly before running off to call Matriarch who got excited upon seeing that she cleaned and boiled them right away. Not exactly right away lah.. she left them in the kitchen sink for a bit. That was when I carried Munchkin to show her the gross-looking, sluggish thingy crawling out. I said "Look Sarah, it's Gary(of Spongebob Squarepants)!" *insert murmurings: what is she teaching her kids?!* Anyway, she screamed out of disgust while trying to move her upper half as far away from the sink as she could.

I was hesitant about putting anything that gross-looking into my mouth but curiosity compelled me. Now I want more. What exactly is siput gong-gong called in English??

I could only find this-
Conchs, Slugs, and Snails: Class Gastropoda
