Your Dexterity score increases by 2 so you can run from things better.

A GIRBBGIRB reaches adulthood at the age of 20 and generally spends the rest of its life in search of someone to accept, or more likely, tolerate it.

Most GIRBBGIRB are neutral good, as they lack the mental capacity to grasp the concept of laws, but try to make themselves appealing (usually to no avail) by acting good (this still doesn't prevent most people from just beating them with a stick on sight though).

GIRBBGIRBs average about 3 feet tall and weigh about 40 pounds. Your size is Small.

Your base walking speed is 35 feet in order to run away.

Because of how detestable the existence of the GIRBBGIRB is, its life goal is just to seek out friends, or even companions that simply tolerate being in proximity to it. Minus 1 d4 times (GIRBBGIRB's level) to all damage the GIRBBGIRB causes, because it just wants to make friends (though it will likely never have any).

The GIRBBGIRB is very easily frightened, due to its small size, and overall tendency to just be beaten by the things around it. You have disadvantage on saving throws against being frightened. Also when under the frightened condition you have 10 feet of increased movement.

Because of the swampy environments in which it is spawned, as well as its just overall pitiful existence, the GIRBBGIRB seems to incessantly Stink Like Hell For some reason. This of course is just one of the many reasons it is often beaten on sight by passerby, and gives you disadvantage on all stealth rolls because they can smell you from a mile away. Also you have disadvantage on all persuasion and performance rolls because of your awful stench.

Due to how easily and often the GIRBBGIRB gets beaten to a pulp by nearly anything it comes across, they have on a genetic level forsaken fighting to some extent, often preferring to flee instead of fight back. This gives you disadvantage on all attack and spell attack rolls you make against creatures, due to your intrinsic fear of violent retaliation.

The GIRBBGIRB dislikes competitive acts such as fighting, and thus can take the Disengage or Hide action as a bonus action on each of its turns in order to try and avoid it.

You can speak, read, and write Common and GIRBBGIRB by cognitively creating sound via rapidly vibrating the leaf-like membranes on your forehead, doing so is incredibly painful for the GIRBBGIRB, but they still put up with it because they want friends that badly.

The primal ancestor of the GIRBBGIRB was the GERBBGERB, it was very similar to a modern day GIRBBGIRB but significantly more vicious and vile. Occasionally the GIRBBGIRB can focus enough raw rage in its frail inner psyche to return to its primal form. This causes the GIRBBGIRB to become significantly more dangerous as its body begins rapidly producing hormones that increase the production of its stench, and cause it to enter an almost berserk state. In this state the GIRBBGIRB loses all previous combat debuffs, incurred by its race and deals an additional 4d8 (times the GIRBBGIRB's level) poison damage whenever it deals poison damage. It also gains resistance to all damage for a single hit, and its movement speed decreases by 10 ft. Finally any creatures who end their turn within a 15 ft radius (centered on the GIRBBGIRB) must make a constitution saving throw, or fall prone due to the noxious fumes being rapidly exuded by its body. This state lasts for 18 seconds and can be used once per long rest when the GIRBBGIRB is at a quarter or lower hp, and at least one allied (player) character (in its party) is downed (on death saves) or outright killed.
