Threesome?

Had a terrific storm in Bukit Mertajam yesterday morning. The gusts of howling wind blew open my partially-closed window and there was rainwater all over my bedroom floor. But luckily, no damage to the bed or table. 

After the storm was over, I went to my flower pots and noticed several snails chomping away on my greens. Yucks, snails. 

Got to eliminate them or else they'll continue to infest my plants. So I placed them aside on the road while continuing to search for more of these garden pests. No more to be found except for these four. 

Found that three of them were now enjoying an orgy of sorts while the disinterested fourth snail decided to slime itself away.
