Flight orb. Though wingless, shen lungs can fly magically due to a magic yellow pearl embedded in their brains. If removed from the dragon, this pearl loses its magic but is still worth 1,000 gp. The dragon can cease or resume flight as a free action.

Scaly command (3/day). Each scaly creature (reptiles or fish but not other dragons) within 25ft of the shen lung are instantly charmed by the shen lung until the creature leaves the 25ft area around the shen lung. A pan lung can speak with any creature charmed by them by this power even if they don't share a language. 

Vermin barrier. No creature that is considered vermin can enter within 60ft of the shen lung giant or otherwise they can't enter the radius willingly. 

Water fire. When a young shen lung is fully submerged in water it gains an aura of ghostly fire which causes any creature to touch or make a melee attack against the shen lung to take 6 (2d6) damage. Other creatures with the water fire ability are immune to this damage. 

Magic Resistance. The shen lung has advantage on saving throws against spells and other magical effects.

Amphibious. The shen lung can breathe air and water. 

Detect thoughts. The shen lung is constantly detecting the thoughts of creatures within 20ft of them. See the spell of the same name if a creature attempts to resist. 

Alternate form. Lung dragons can assume any humanoid form of Small to Large size as a standard action. This ability is similar to the polymorph spell but allows only humanoid forms. Whilst in this form they have advantage on all checks to hide their true self. 

Innate Spellcasting. The young shen lung's innate spellcasting ability is Wisdom (spell save DC 14). The young shen lung can innately cast the following spells, requiring no material components:

At will: bane, bless, invisibility, plane shift

Multi attack. The young shen lung makes a bite attack and two claw attacks. 

Bite. Melee Weapon Attack: +6 to hit, reach 10 ft., 1 target. Hit: 9 (2d6 + 3) piercing damage. 

Claw. Melee Weapon Attack: +6 to hit, reach 5 ft., 1 target. Hit: 7 (1d8 + 3) slashing damage.
