The Goblin Council of Elders has answered the YGCA's prank.
Combining their ancient wisdom and latent magic, the Elders assembled into a colossal Voltron-like construct called Eldertron and unleashed a fiery inferno on the Young Goblin Chaos Association's headquarters. Eyewitnesses saw a blinding flash, heard a deafening roar and then watched the YGCA's building become a smoldering crater. The resulting fireball, rumored to rival the Tsar Bomba, was visible for miles and cast an orange glow over the nation for most of the night.
"Those young whippersnappers needed a lesson in respect," cackled Elder Gnarltooth, who formed the left leg. "We showed them the Elders are not to be trifled with."
Gnarltooth then praised the YGCA's audacity, said the prank had "earned their respect," and announced that the Council would rebuild the headquarters with the doubled funding it gave the YGCA last week.
"We can afford a new one," he chuckled, surveying the ruins. "And a little destruction is good for the goblin soul."
The YGCA has vowed to rebuild and is already planning its next prank. "This time," said a spokesgoblin, "we're aiming for the moon."
