Dainty is a man that Gran set a trap for in Weighting Is the Hardest Part
He is one of Gran's exes in My Big Fat Gran Wedding and it's pointed out how much Clop resembles him.
In Crood Detente he is the only holdout who doesn't like the Broods but when Grug thrusts him in the middle of the activities the other Valleyites are enjoying it causes them to turn against each until until Dainty is the ONLY one who likes them.
