This article focuses on the interactions between Cro-Marmot and every other main character he has interacted with.
Despite being encased in a block of ice and being completely silent, he actually interacts with a lot of characters on the show and gets along with most of them. Some of his interactions are only made up of him giving ice cream to other characters.
- Main article: Giggles-Cro-Marmot Relationship
They have interacted several times and appear to have a very neutral relationship. Both characters meet in A Change of Heart when Lumpy buys meat from Cro-Marmot's butchershop. In Wipe Out! they are enemies, as Lumpy laughs at Cro-Marmot when the latter falls off his board, which makes Cro-Marmot freeze the ocean. However, in In a Jam, Lumpy is awed by Cro-Marmot's guitar skills. Cro-Marmot was also one of the performers at Lumpy's circus in Mime to Five.
In In a Jam, Handy is impressed with Cro-Marmot's guitar playing.
Their main interaction with each other is in Wipe Out!, in which Nutty purchases an ice cream cone from Cro-Marmot's truck. The interaction is very brief and ends quickly. Cro-Marmot also sold meat to Nutty in A Change of Heart.
Just like Handy, their only interaction together is in In a Jam, where he is impressed with Cro-Marmot's guitar playing.
The two characters might have possibly interacted offscreen when Cub went to buy a popsicle from Cro-Marmot's ice cream truck in A Hole Lotta Love.
They are seen waiting near a bus stop together in Ipso Fatso. Flaky gets annoyed by him when she is hit in the head by Lumpy's fist, thinking is was Cro-Marmot who did it. They also perform tricks at a circus together in Mime to Five.
These two characters have been together several times, but there isn't much of a relationship between them. In From Hero to Eternity The Mole is standing on Cro-Marmot as they are both being sucked into a hole in the ground. In A Change of Heart, The Mole holds up Cro-Marmot's line at his butcher shop. In Wingin' It, The Mole checks Cro-Marmot for contraband, before he can get on the plane. In Wipe Out!, The Mole sticks the surfing trophy in Cro-Mamrot's ice and walks away.
Cro-Marmot and Russell are shown to be good friends in Can't Stop Coffin, where they play baseball together, along with Cuddles and Toothy. They also appear together in See What Develops at the grand opening of a supermarket.
Like most other characters, Cro-Marmot is enemies with the raccoon brothers. They kidnap him in Swelter Skelter so they can stay cool from the heat.
Mime is clearly annoyed at Cro-Marmot for buying the unicycle he was planning on getting. However, in Brake the Cycle they both appear to be friends and are enjoying a picnic together. Mime also made a balloon hat for him in See What Develops. Cro-Marmot also sold meat to him in A Change of Heart.
Unlike a majority of the characters, Cro-Marmot isn't really into Splendid. In Wrath of Con he's one of the few characters who don't associate with Splendid, he instead sells his own merchandise. His only interaction with Splendid so far occurred in See What Develops where Splendid was shown annoyed at Cro-Marmot for occupying a phone booth.
