From the How to Train Your Dragon Wiki:
- "From the sidelines of the battlefield comes the Prickleboggle. There is more than meets the eye with this dragon; don’t be deceived by its lack of combative abilities, they are still an impressive addition to your stables. What they lack in a fight, they make up for in their calming and healing talents in some of the most chaotic of circumstances. These dragons have essential healing powers, powers that help them bond to some of the most ferocious of dragons, who are often very loyal to them after being healed.
- "To avoid attacks, Prickleboggles have defensive skin, which prevents them from being harmed while they tend to their fallen dragon friends. Not to say that they are impenetrable to fiery attacks, but they have evolved to thrive through quick attacks when aiding friends in battle.
- "While this dragon is known for being one of the more peaceful of creatures to fly across Berk, it is important to remember that it also has an essential function to heal and calm, making for the ultimate addition as you grow your fleet of winged companions."
