Baby Griffon

Keen Sight. The Baby Griffon has advantage on Wisdom (Perception) checks that rely on sight.

Clumsy Flyer. The Baby Griffon cannot sustain flight for more than one turn.

Trained Mounts. A griffon raised from an egg can be trained to serve as a mount. However, such training is time consuming, expensive (mostly for the ample food the creature requires), and dangerous. Expert trainers well versed in the griffon's legendary ferocity are typically the only ones able to raise these creatures safely.
Once trained, a griffon is a fierce and loyal steed. It bonds with one master for life, fighting to the death to protect that rider. A griffon mount retains its ravenous appetite for horseflesh, and a wise master ensures that a griffon remains satiated with other prey when passing through civilized lands. Will be able to ride when it is grown

Beak. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 3 (1d4 + 2) piercing damage.

Claws. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 4 (1d6 + 2) slashing damage.
