Heliowl

Heliowl (Helium Bluejayowlis) is a species thriving in the Kingdom of Knowledge's forests.

Origin
The Heliowl evolved/mutated from a crossbreed between the Bluejay and Owl. However, after Dr. Com-Poundyou's accident warped the environment, the crossbreed mix combined with Helium (a living compound). The result was the Heliowl as we know it today. However, the fallout of the accident left the Heliowl's feathers dusted with chemical debris, thus leaving the bird's once sparkling coat a dull matte.

Nature
The Heliowl is a strange animal. Perhaps the most intriguing aspect is it's reproductive habits - as Helium's atomic weight is roughly 4, the Heliowl can only produce four chicks per year. Because the rate of deforestation due to chemical pollution (from improper disposal of chemicals) is high, the animal's population is dwindling into hundreds. However, the Heliowl's partially-helium-based bones allow it to soar higher than any other species of avian creature ever seen before.
