Crimson Pine is a plant that first appeared in "Grumblegard, Part 1".
The Crimson Pine is a fictitious pine species. It bears a resemblance to Red Pines. They have tall, straight trunks, crowned at the top with sloping branches of long, dark green needles. The bark is a characteristic crimson color.
Crimson Pine is edible to dragons and the main food source of the Piercing Shriekscale.
After rescuing two Piercing Shriekscales in "Grumblegard, Part 1", the Rescue Riders found out that the hatchlings would only eat Crimson Pine bark. Dak, Winger, Aggro, and Burple set out to find it, while the others took care of the babies. The group went straight to Hazard Island, where they found the Crimson Pine. After a few struggles with the owner of the island, Grumblegard, Dak managed to take enough bark to fill a bag, and then returned to Huttsgalor, where he fed the baby dragons.
In "Grumblegard, Part 2", after the Rescue Riders made peace with Grumblegard, they took more supplies of Crimson Pine bark from Hazard Island. However, after a short while, Grumblegard decided to adopt all the hatchlings that the Riders took care of, and they returned to Hazard Island, leaving the Crimson Pine bark at The Roost.
