Leckordragons

Here is a new creature in killer island deserts that I imagine: So, I think it should be called a Leckordragon. It has Spikiness, +2 Defense, +5 Strength, and +3 Speed, and it lives for 50 days. Make it a spotted yellow lizard that has a shiny blue tail, with a small chance of being black. Make it have the build of a lizard and a lizard tail but with cat paws and the head of a leopard, and give it dragon wings. Make the lizard tail have many spines on, giving it Spikiness. Make it able to shed it's tail and give your creatures free meat if it goes down to 15 HP, bringing it's defense stat down to one and removing the spikiness stat, but also giving it the ability to fly if attacked. It's tail will not regenerate enough to give it the old stats, instead being much shorter with almost no spikes.

All leckordragons are able to eat cactus fruit, are immune to it, and heal one damage point if they do eat a cactus fruit. Flying leckordragons are only flying for the next two turns if they are attacked, and generally flee if they are attacked by a creature, and they are on the ground at all other times. Flying leckordragons do not change or regrow their tail if they heal and go above 15 HP, as the effects are permanent. Leckordragons eat both bearyenas and nichelings, and do not attack other animals.

Okay, thank you for adding the credit, PopsicleNinja! 

Maybe they can be befriended like bearyena, and that's where we can get our leathery wings? The other parts you mentioned would also be interesting to inherit.
