I hope you've enjoyed the monsters so far. I'm having a lot of fun with this mini-marathon.
Mud and wet grass stick to what appears to be a baby crocodile. The gleam in its eyes belies the intelligence possessed by the creature.

Breath Weapon (Su) A creature that fails its Reflex save against a lake kaida’s breath weapon is knocked prone.
Emergency Summon (Su) A lake kaida can spend two uses of summon nature’s ally III to use the spell-like ability as a standard action.
Lake kaidas are dragons sworn to protect lakes, ponds, and other small bodies of water. They typically do this by attempting to frighten away trespassers with their breath weapon and spell-like abilities. They prefer to summon water elementals but will summon animals such as crabs and crocodiles to handle foes in and out of the water. As a last resort or against particularly foul despoilers, lake kaidas transform themselves into crocodiles, usually after grabbing hold of an opponent with their less-powerful bites.
Lake kaidas befriend druids and nixies who also have a vested interest in protecting hidden waterways. When they aren’t actively defending their homes, they take an interest in managing the lives of animals where they live. They ensure overpopulation doesn’t occur, allowing natural predation to take its course, and, on the other side of the coin, cultivate animals with declining populations.
Lake kaidas typically measure 1 foot in length and weigh 25 pounds.
A neutral spellcaster with the Improved Familiar feat and animal companion class feature can gain a lake kaida as a familiar at 7th level. The lake kaida will leave the spellcaster if it is does not visit a natural waterway at least once a week (the spellcaster can attempt to negotiate with the kaida in extreme circumstances such as planar travel).
