Rhamphorhynchus - The Potential Ox Pecker
The way that Rham feels rn is that it seems very in favor of helping others with debuffs for scraps, but what if there was a friendlier alternative. Give it an insectivore diet, in which, you can groom larger dinos by picking 'ticks and other parasites', doesn't need to be a model, just flavor, but in doing so, gives the Rham some food and water, while giving a stamina and health regen buff, or something like that, unsure, feels fitting, to the dino it fed off of!
