Keen Smell. The young tiger lily has advantage on Wisdom (Perception) checks that rely on smell.

Pounce. If the tiger moves at least 20 feet straight toward a creature and then hits it with a claw attack on the same turn, that target must succeed on a DC 13 Strength saving throw or be knocked prone. If the target is prone, the tiger can make one bite attack against it as a bonus action.

Pounce of Surprise. If the young tiger lily is hidden, it may move 15 feet and that target must succeed on a DC 13 Strength saving throw or be knocked prone. If the target is knocked prone, the beast, instead of attacking,  may release a cloud of spores, the target must make a DC 13 Wisdom saving throw or become charmed. Otherwise the tiger lily may make both a bite and claw attack

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) piercing damage.

Claw. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 4 (1d4 + 2) slashing damage.

Veil of Flowers.  Upon receiving damage, the tiger lily may let out a roar sending the surrounding foliage into a surge of growth, providing the beast invisibility until the end of its next turn. 2/short rest
