This is the latest entry in a series of Mars Attacks! creatures I converted for Fifth Edition Dungeons & Dragons. You can download all the monsters here.   

An enormous green caterpillar over a thousand feet long twines its way around buildings.

Martians uses these green horrors as heavy artillery, sending them winding through enemy troops and destroying all structures in their path.

Siege Monster. The monstrous caterpillar does   double damage to objects and structures.


Bite. Melee Weapon   Attack: +10 to hit, reach 10 ft., one target. Hit: 17 (4d6 + 5) piercing   damage and the target is grappled (escape DC 15). If the target is Large   or smaller, it is also restrained until this grapple ends. While grappling   the target, the monstrous caterpillar has advantage on attack rolls against   it and can't use this attack against other targets. When the monstrous caterpillar   moves, any Large or smaller target it is grappling moves with it.

Chew. The monstrous caterpillar   chews on a nonmagical ferrous metal object it can see within 5 feet of it. If   the object isn't being worn or carried, it destroys a 10-foot cube of it. Beings   trapped inside the object can dodge jump free with a DC 14 Dexterity saving   throw. Failure means each target is subjected to a bite attack as a bonus   action.
