Carny Plocodile

Hold Breath. The crocodile can hold its breath for 15 minutes.

False Appearance: While the carny remains motionless, it is indistinguishable from a rotting log with tufts of high grass or cattails growing around it. Once it has been spotted it can no longer benefit from this trait. 

Hydronic Healing: At the start of it's turn it heals 1d10 as long as it is standing in water. 

Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one creature. Hit: 7 (2d8+ 5) piercing damage, and the target is grappled (escape DC 14). Until this grapple ends, the target is restrained, and the crocodile can't bite another target.

Swallow: After 1st bite, the target can be swallowed as an action. 

Grasping Tendrils. The plant can have up to 2 tendrils at a time. Each tendril can be attacked (AC 13, 10 hit points). Destroying a tendril deals no damage to the plant, which can extrude a replacement tendril on its next turn. A tendril can be broken if a creature takes an action and succeeds on a DC 13 Strength check against it.

Entangle (Recharge 5-6). Grasping roots and vines sprout in a 15 foot radius centered on the plant, withering after 1 minute. For the duration, the area is difficult terrain for non-plant creatures. In addition, each creature of the plant’s choice must succeed on a DC 12 Strength saving throw or become restrained
