Crimson Snapper Birdtrap

Legendary Resistance (2/day). If the Crimson Snapper Birdtrap fails a saving throw, it can choose to succeed instead.

Spider Climb. The corpse flower can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.

Wingbite Cloud. A thick cloud of plant spores emanating in a 30ft radius from the Crimson Snapper. All creatures in the cloud are heavily obscured by the abnormally thick spores. Each creature that starts its turn within the cloud must make a DC 14 Constitution saving throw, unless the creature is a Construct or an Undead. On a failed save, the creature is infected with the Wingbite disease. On a successful save, the creature has advantage on it's saving throws to resist the disease for the next 24 hours. If they have the disease, they cannot get it again and do not need to make this check. 

Wingbite Disease. If a creature is infected with Wingbite they must make daily DC14 Constitution checks. On a failed save they lose 5ft flying speed if they have one. If they do not, they can still be carriers of the disease until cured. On a successful save they resist the disease's effects for 24hours. After three successful saves total, they fight off the disease naturally. A Lesser Restoration will cure the disease as well. After being cured, a creature with a flying speed will take a week to regrow it's lost feathers enough to regain it's lost fly speed.

Multiattack. The corpse flower makes three Tentacle attacks.

Tentacle. Melee Weapon Attack: +5 to hit, reach 30 ft., one target. Hit: 9 (2d6 + 2) bludgeoning damage plus 10 (3d6) poison damage. If the creature is Medium or smaller, it is grappled (DC 13 strength save to escape).

Pod Launcher. The Crimson Snapper regurgitates a pod of undigested bugs from its stomach and launches it to a space up to 120 ft away. Summons one swarm of insects determined by rolling 1d4. 1=Beetles, 2=Wasps, 3=Centipedes, 4=Rot Grubs.

Drag to Doom. If the Crimson Snapper has a creature grappled, it pulls target 15 feet closer to the Snapper each turn until it is in the same space. Once there, the target is closed within one of the Crimson Snapper's many mouths and takes 2d4 acid damage. Target creature is no longer grappled and is now restrained. A creature within 5ft of the Crimson Snapper can attempt to free a restrained creature or it's self with a DC15 Strength check.
