PLAIN STRIDER

Number Appearing: 1-4

Size: Twenty to forty feet tall

Armor: Tough chitinous shell on lower extremities, tentacles and exposed brain soft and squishy, 100% proof against acid, ooze attack

Resilience: Attacks on legs like chopping down good sized tree, brains and soft bits more vulnerable

Intelligence: High but utterly unconcerned with the affairs of lesser beings

Communication: Emits rhythmic ululations, mostly subtle derivations of popular Plain Strider songs 

Disposition: Smug superiority of creature that sits atop the food chain

Violence: Tentacles seize prey, deliver to huge parrot-like beak concealed in lower body cavity, stuns prey with sonic attack (the Song of Hunting), smash or kick with feet

Enemies: None as such, but regards anything human size or smaller as prey

Aims: Hunt and feed, composition/performance of songs

Peculiarities: 

- Apex predator of the Great Lichen Plain, an improbably vast cavern of broken rocky terrain covered with unique variety of growths, teeming with oozes, slimes, puddings and jellies

- Hunts puddings and oozes primarily, but always willing to try something novel

- Communicates via humpback whale-like songs when necessary, mostly sings to express itself as artistic exploration of its nature and place in the cosmos, individuals in constant competition for place in the Plain Strider Top Ten

- Quickly stomp out any non-Striders who attempt one of their songs

Treasure: Beaks sought after by Underworld sentients as raw material for building projects/giant-size armor, sometimes fashioned into the hulls of vessels meant to navigate the Black Ooze River
