Dave & Ping Pong(friends)
Joe Murray, creator of Camp Lazlo, originally created Lazlo for a children's book concept. As he developed the concept, Murray believed that a children's book could not contain the stories and ideas, so he decided to create a television show.  According to Murray, when he thought about Lazlo's personality, a Brazilian spider monkey came to his mind.  Originally Murray wanted Lazlo to carry a strong Brazilian accent, but when Cartoon Network asked Murray to choose only one character to carry a strong accent, Murray opted for Raj and gave Lazlo an Americanized voice.  Murray said that he did not plan for Alazraqui to voice Lazlo; according to him the arrangement simply occurred. 
Lazlo is an orange spidermonkey with yellow lips, he wears a greenish tan T shirt, bright red neckerchief, black pants/shoes, greenish tan beanie hat with blue stripe.
Lazlo stays in the Jelly Cabin with Raj and Clam; the three are called the "Jelly Cabin Trio." 
The Cartoon Network press kit character descriptions describe Lazlo as "imaginative, freethinking," and a "natural-born non-conformist." The press kit states that Lazlo "enthusiastically spreads mischief and wacky shenanigans," uses "imagination and creativity" to solve problems, and annoys Scoutmaster Lumpus with his "persistent happiness and optimism." 
Raj, Clam and Lazlo are best friends, since they live together in Jelly cabin. They do many things there including hide, play and act funny.
The Hollywood Reporter reviewer Ray Richmond described Lazlo as "energetic." Science Fiction Weekly reporter Kathie Huddleston describes Lazlo as "optimistic" and "out to wreak as much good-natured havoc as he can." Common Sense Media reviewer Joly Herman, whose review is posted on Go.com, says that Lazlo possesses "innocent rebellious quality of a trickster" since "authority" is often his adversary, and that Lazlo does not "take him seriously," with "him" being Lumpus.
Murray says that he admires Lazlo's ability to "make the best of situations when things go against him." In an interview the interviewer inquired Murray about Lazlo's dislike of "structure." 
Murray also describes Lazlo as dealing with conflicts and issues "with imagination"; the Camp Lazlo creator said that in his own family he likes to use "imagination" when dealing with his real life conflicts.
A member of the Squirrel Scouts, Patsy Smiles, has a crush on Lazlo. In an interview Murray said that Patsy's affection causes Lazlo to feel "little freaked out" and that "She scares him." He describes Patsy as "a little more aggressive with Lazlo than he would ever reciprocate."
