I remembered I'd forgotten to post this race, so I figured I should get it up and shared with you. The Grippli are a neutral with good inclinations race of humanoid tree-frogs who actually date all the way back to 1st edition, having first shown up in TSR's Monster Cards in 1982 and subsequently appeared in first edition's Monster Manual II. They went on to reappear in the first Monstrous Compendium Appendix for Greyhawk and then in the Advanced Dungeons & Dragons Monstrous Manual for 2e. They received PC writeups in Dragon Magazine for both 2e (#262) and 3e (#324), and even made the jump to Pathfinder in the Advanced Race Guide. With so much lore, and so many different racial options - from their original psionic selves to their more primitive depictions in Dragon to their abundance of racial options in Pathfinder - I... well, I may have gone a little overboard.

Patagia: So long as a Treetop Grippli is not restrained, paralyzed, encumbered, equipped with medium or heavy armor, or otherwise rendered immobile, it takes no damage from falling distances. When falling, it may move forward, covering a horizontal distance equal to half the vertical distance travelled. At 5th level, a Treetop Grippli gains a Fly speed of 10 feet.
Treetop Dweller: A Treetop Grippli loses its Swim speed entirely.

A Civilized Weapon: A Princely Grippli has automatic proficiency with either the Rapier or the Longsword, chosen at character creation.

Psionic Grippli

Amphibious Sagacity: A Psionic Grippli can communicate telepathically with one creature at a time, so long as both it and the desired creature are within 30 feet of each other. Additionally, a Psionic Grippli can cast a variant of the Mage Hand cantrip at will, using Wisdom as its casting ability score. This variant follows all of the normal rules for Mage Hand, but the “hand” is invisible.
Grippli Feat: Agile Tongue
Some gripplis have learned to master their tongues to the point of wielding them with preternatural dexterity.
Prerequisite: Grippli
Effect: Your grippli’s tongue can now be used like a third hand, allowing you to reach objects up to 10 feet away. When using your tongue like a limb, halve your Strength score, rounding down, for the purposes of determining what you can carry, making attacks, etcetera.
