Despite the fact that Ella likes her, she doesn't like Ella back.
In the episode 'Mo Money, Mo Problems', she ratted Ella out to Chris so that the latter would get eliminated for singing when Chris told her (Ella) not to, even though it was the only way to save Dave from a bear.
In her debut episode, she gave Topher a death threat.
During the "Truth or Scare" challenge, she ate a tarantula (albeit by accident).
Throughout the episode, This Is The Pits!, she constantly attempted to keep Dave and Sky apart from each other.
In the episode, Pahk'd With Talent, Sugar antagonized Sky after their alliance is over.
Hypocrisy: She detested Ella's singing, yet she gleefully sings commercial jingles that sound far worse than any of Ella's songs.
Her performance, Craptry (Country and rap), failed to impress the judges. Not to mention her falsetto caused damage to the island. This caused her to get eliminated.
She farts several times, including in her audition tape after saying "nailed it".
She often had Ella eliminated from the season due to her singing, which is stupid and unfair.
Passable character design.
Some might found that she was somewhat funny.
Rochelle Wilson did a decent job voicing her.
She shares her similarities with Heather.
Both are labeled "Queens", have a conflict with a "Princess" whom they eliminated.
Sugar, along with Tyler and Dakota, are the only contestants to have competed in a beauty pageant.
She is the only female character with a gap in her teeth (not counting Heather, since she originally didn't have a gap).
She is a parody of Alana Thompson aka Honey Boo Boo.
