Grug feels like he and Thunk are growing apart and decides to go for a day of bonding.
Tropes for this episode include:
- Generation Xerox: When Grug interrogates Phil, Phil remarks that Thunk looks to him as a paternal figure because of Grug's "neglect, indifference and general sloth", three adjectives that also describe Thunk.
- Genius Ditz: While Thunk has been portrayed as a Lazy Bum and The Ditz up to this point, it's here do we see that Thunk actually does pay attention when watching window, learning how to frighten off Bearacudas and ward off other predators.
- Parental Substitute: The episode kicks off when Grug overhears Thunk call Phil "dad", worried that Phil might be replacing him. In a rare moment of clarity, Grug acknowledges that it's more his fault than Phil's and actually asks for his advice.
- Sentimental Homemade Toy: One of Phil's most prized treasures is a small stick statue Dawn made for him when she was little, becoming genuinely nervous when Grunk starts handling it for fear that he would break it.
