WoTC has been known to use existing creatures and “skin” them for use as other creatures. (i.e. "DDAL06-02 The Redemption of Kelvan" contained a clockwork wyvern construct that had stats based on a regular wyvern and Tomb of Annihilation had clay warriors based on NPC gladiators.)
Is there any creature that resembles Warframe's desert skate or that could easily be skinned as one?
We would be looking for a creature with three functions: a poison tail, dig movement and an elevated challenge rating > 1.
As a clarification: we are not looking for a creature that looks like a skate - but rather, similar to how WotC skins their creature, find a creature that has the same fundamental skills as listed above.
