Beth has many traits of this, such as her Ugly Cute appearance and how sweetly yet awkwardly she acts when she interacts with the other characters.
Noah. While this term is used to describe Ho Yay between him and Cody, his actions in the Paris episode of World Tour and his attempts to impress Emma in The Ridonculous Race proves that he on his own certainly counts.
Ezekiel, believe it or not. Though not normally this (his social naivety is usually portrayed as awkward rather than cute), he has a moment in the Island special: after Beth and Lindsay allow him to join up with them on the condition that he isn't sexist to them, he's absolutely overjoyed at the idea of having friends and shakes Beth's hand so hard her glasses nearly fall off.
Harold is the show's poster boy example, being a klutzy nerd who just wants to make a name for himself and impress everyone. He also has an arc of trying to win over Leshawna, which is quite endearing to watch.
Lovable Jock Tyler has plenty of such moments in World Tour, between imitating a goat for Lindsay, revealing his love for Japanese game shows, and getting extremely excited and happy when Lindsay finally remembers him. Even in Island, though, his sheer earnestness earns him a lot of points in this.
From the second generation:
Cameron's diminutive appearance and wide-eyed nature definitely make him this to some. Zoey certainly believes so, even when she enters commando-mode.
Mike's tall and gangly appearance, shy and sweet nature, and Childish Tooth Gap make him quite lovable in his own special way.
Sam. Between his love for video games, self-deprecation, and initially-ineffectual attempts to win Dakota over, he's got this down pat.
From the third generation:
Max, the aspiring supervillain whose attempts at being evil always backfire. He's later revealed to have a soft spot for kids, and states that he never spent his life being social.
Dave, a hypochondriac who often freaks out when he gets remotely dirty and has a tendency to get himself in awkward situations, such as accidentally kissing a bat on the lips, climbing out a confessional toilet, and accidentally telling Sky he's glad she was stung by bees instead of him (believing he's allergic to bee stings).
Subverted with Scarlett, who only looks and behaves like the shy, nerdy, and intellectual bookworm she's initially presented as, and is in reality, a cruel and psychotic Bitch in Sheep's Clothing and Nerdy Bully.
Both members of the Father & Son team. Junior's attempts to show how much of a "man" he is can come off as a cute dork, while his father Dwayne's attempts to be cool with the younger and hipper contestants come off as endearingly awkward.
Adversity Twins Mickey and Jay are small and frail teenage boys who thoroughly support each other at every turn of the race and possess little social experience, especially involving "cute girls".
