This article focuses on the interactions between Lammy and every other main character she has interacted with so far.
As a new character, Lammy has yet to interact with several members of the cast. She is, however, on good terms with almost every character she has interacted with so far, however her close friendship with Mr. Pickels ruins this most of the time.
Lammy's only interaction with Cuddles occurs in You're Kraken Me Up, where they're seen standing next to each other while Lumpy performs CPR on "Giggles", inferring that they may have a neutral stand in relationships.
Lammy seems to like Giggles as evidenced in Royal Flush, where Giggles goes over to Lammy's house and plays poker.

Unlike everyone else she has interacted with, Lammy and Lumpy are not fond of each other. In A Bit of a Pickle Lumpy arrests Lammy and tases her eye, and in All In Vein Lammy is killed by a vampire Lumpy. Lumpy also accidentally kills Lammy in All Work and No Play.
Not counting Mr. Pickels, Petunia is arguably Lammy's closest friend. They have a brief tea party in A Bit of a Pickle. In Royal Flush, Lammy invites her to play poker in her house. Petunia is also the first character Lammy met, if not counting Mr. Pickels.
So far, Handy's only interaction with Lammy is in A Bit of a Pickle, in which she accidentally runs him over while trying to stop Mr. Pickels.
Lammy goes to the park with Nutty in All Work and No Play indicating a close friendship.
Lammy and Sniffles are seen as friends, as they go to the park together in All Work and No Play.
Flaky and Lammy's relationship seems to be neutral.
In A Bit of a Pickle, Flaky seems horrified when she sees Lammy unintentionally killing Petunia and speeds away from her, seemingly going to alert the police. However, she goes to Lammy's poker party in Royal Flush. Lammy even lets Flaky eat her sandwich, seeing as how she only prepared three sandwiches thinking only her, Giggles, and Petunia would be the only ones at her house.
- Main article: Lammy-Mr.Pickels Relationship
Lammy and Mr. Pickels are best friends, albeit in a very dysfunctional relationship. Mr. Pickels is shown to kill other characters that Lammy socializes with to presumably prevent others from stealing his friendahip with her, as seen in A Bit of a Pickle or Royal Flush. However, Lammy still takes him with her wherever they go despite this, an example being Spare Tire or The Chokes on You.
- She has yet to interact with Toothy, Pop, Cub, Lifty, Shifty, The Mole, Disco Bear, Splendid, Mime, Flippy, Cro-Marmot and Russell.
