Obosh

Obosh the Preypiercer is a legendary hellion horror from the plane of Ikoria.

When the planeswalker Vivien Reid encountered the monstrous Obosh, her irrational first instinct was to count how many legs it had. However, she later realized it would be better to do so while keeping a safe distance from the monster. At some point, Vivien managed to count how many legs Obosh has: the answer is 347.
