Gribbits (originally named Gribbons, but no one cared) is the lawyer appointed the Dragon Friends when they were on trial at Frisko's Camp. He is tricked by Freezo to serve as their Champion during the Trial of Cunning. Despite his protestations, when they escaped, they took him with them. He escaped from them at the outskirts of Waterdeep, but they met him again working for Janos Meer, when they again forced him to go with them, this time by Philge strapping him to her chest.
Gribbits hates the Dragon Friends, and simply does not want to be with them.
They meet him again in the first season of Tomb of Annihilation. He becomes more comfortable and friendly with the Dragon Friends after Philge attaches a chain to him and hurls him at an enemy, using him as a makeshift flail. This earns him the nickname "Gribbits The Weapon". During this adventure, Philge also noted that Gribbits has a bad dong.
When the Dragon Friends are being tried for the murder of Hyperion Max on Primus, they are given the chance to summon legal representation from anywhere in the multiverse. Freezo immediately requests Gribbits be summoned, and he is plucked from the middle of his wedding. After doing his best to secure a plea bargain for the Friends, Gribbits is dismissed, sent back to "approximately" the same time and space from where he was taken, but it is implied his bride may have already left him for an old boyfriend, assuming he had jilted her at the altar.
Gribbits appears prominently in the adventure module The Gribbits Detective Agency, in which he hires the player characters to investigate Janos Meer's disappearance.
