Sphagnerodontes (PvZ2)

Sphagnerodontes is a plant created for Jurassic-themed levels, and that needs to be planted on water. When he is placed, he will create a small nest on a tile, undestroyable to by normal means, and while start travelling back and forth on his lane, biting zombies as they pass by. They are invincible, but their nests can be crushed by certain zombies or Big Wave Beach's tide make their nest get out of the water, in which case they will simply left by the zombie's side

Origins and appearance
He is based on the Sphagnum, a small species of moss growing in bogs since the Paleozoic, and the Sphaerodontes, a genus of ichthyosaurid that lived during the Late Jurassic in the seas of Cuba

He has the classical shape of an ichthyosaurid, but has leaves as a skin, and his flippers are large and yellowish leaves. He bears two small cute eyes, will produce small splashe when he swims and is only 1 tile long. The nest is a small rock, with a few sphagnum leaves outside

Plant food effect
When fed Plant Food, he will get at the back of his lane, grow at thrice its size and rush down the lane, inflicting 900 DPS and knocking back every zombie by 4 tiles

Strategies
Usable only on levels with water, he will deal a small quantity of damage, but can attack all zombies, as long as they are on water tiles. They are very efficient in large numbers, and usually won't get killed, excepted if the tiles their nests are on gets dried out, so you should place them near the zombie's side to decrease their chances of getting affected by the tide ; the only other way for them to get killed is to have certain zombies crush them, which can only happen in Pinata Parties if it is a Big Wave Beach level. They isn't much you can do to increase their efficiency ; slowing down or stopping zombies can give less time to the Sphagnerodontes to bite them, but knocking ennemies back a bit can allow it to bite them more if he is going in a certain direction. They can also kill very quickly Surfer Zombies if they are going in the same direction, which is more likely to happen if you can clog the lane with this plant
