Keeping an Eye on you
A beautiful green coloured snail/slug with lots of 'yellow coloured bumps' all over.
Am not sure if the ID is correct as Ibycus rachelae was discovered from high altitude forest (around 1,900 masl) in Sabah, Borneo and described in the year 2008. The picture here is from Pahang, West Malaysia. They do looks very similar though.
Its common name is Ninja Slug as there's more to the name than meets the eye: The slug species makes use of so-called love darts. Made of calcium carbonate, the love dart is a harpoon-like structure that pierces and injects a hormone into a potential mate. The dart could increase the slug's chances of reproduction.

Ibycus rachelae, the Long-tailed slug, is a slug that was previously thought to be known from Sabah/Borneo but is not also documented in certain highlands of Peninsular Malaysia.
