After years of sketching and brain storming, I finally settled on a design for my leupself!

He uses male pronouns (for any of you unfamiliar with leupaks, they all lack a biological sex) and his concept is the new zealand glow worm (though he's... a very blue version aha, maybe a shiny or something)

His venom's clear and really really sticky, much like the actual glow worm's mucous, which they hang from silk in pretty little drops that look like clear beads! He also has a REALLY long tongue that he dangles underneath himself covered in sticky venom, since he can't exactly make silk. His facet allows him to climb any surface, so he can just stick to the ceiling of a cave or a stalactite or something and just wait for someone/something to get stuck and then pulls them up to get a better grip on them and then feeds (since I get the feeling trying to siphon blood through the tongueclaw when it's too long is nearly impossible)

Also, his body is slightly translucent, and even more so on his belly and the end of his tail. His tummy glows because of his eggsac, and the end of his tail has a glowing gland, very much like a glow worm's. It glows brighter when he's hungry.

And uhhh yeah!!
My better half made himself a leupself too, and it's really cute, you should go look, yeeee

IF YOU WANNA LEARN MORE ABOUT LEUPAKS, Leupstripes is their creator, so your best bet right now is to go check their gallery out! (Which you should do anyhow since their stuff is really great)
