From SqueezyBuns:

“Journeying through a jungle continent of giants, dinosaurs & drow cultists isn’t easy…That’s why My party decided to ride in style! Purchasing a Brontosaurus in the city of Stormreach, and equipping it with a makeshift home, they ventured out into the wilderness seeking answers, glory & riches!

Naming him Rumble the Friend, they fought off giants, drow, and even survived an encounter with a roc, most certainly Rumble was worth the investment of gold when they emptied their pockets.

Equipped with a rudimentary home, a handful of ballista, and plenty of rope to hold onto the big fella when needed, there is nothing the jungle can throw at this beast that they couldn’t handle! That was until they reached the mountains…”
