バブルスライム
from Monster Girl Encyclopedia
Origin
Wet areas, sewers, etc
Bubble slimes are probably the gloomiest members of the slime family. Making their homes in dank caves and the sewers of human settlements, they hunt for semen to eat just like their basic cousins. Alas, they are both slower and rather more malodorous than the other slimegirls, meaning you can smell them coming a mile away and make a quick escape. The bubble slime's scent comes from the bubbling chemical reactions that are constantly happening in their body, which actually effect a purification of the toxins they encounter in their environments - meaning, ironically, that they're probably the cleanest thing in their vicinity. In fact, jelly made from the bubble slime's goo is considered an exquisite delicacy in the Demon Realm Traveller's Guide. Although bubble slimes are slow, if they do catch you, they have a cunning method of ensuring you can't get away from them (or at least not for long). The first technique on attack is to force their victim to swallow some of their jelly with a kiss. It's an extremely addictive aphrodisiac, so it tends to discourage escape.
