Groblins, a disastrous pen and paper rpg

To clarify, Groblins is a pen and paper rpg where a party play a bunch of sad little weird goblins (called Groblins). I want the RPG to feel like you're piloting sentient racoons, just getting into trouble and adventures, digging through a villager's trashcan.

The concept came from a few places but mostly this:

Froglins, which are kinda like Groblins, but are wet and slimy. They tend to launch at foes while in a panic. Good at jumping and climbing, giving nice vertical movement options. Often seen in ponds attempt to convince passersby that they are actually ducks that deserve bread. (Faster when wet and unlikely to be grappled)

Kobolds, little funky lizard dudes. They are often found in dungeons, much to the dismay of human adventures. Kobolds eat gems, believing that it'll eventually turn them into a dragon. As such, many gem necklaces found in dungeons often have Kobold bite marks on them. (They can gain +1hp permanently if they consume a high value gem)

Also my deciding factor on playable races is; "Would they be really annoying for adventures to deal with?"
