Snuggles has been Luna's best friend since the day she was born. Luna and Snuggles are so close that, in their Teen years, Luna devoted hours of her time to discovering Imaginary Friend Metamorphium in order to take her to prom. When she couldn't do it in time, she tries again as a Love Day tribute and succeeds.
Snuggles is introduced in Part 7, when Baby Luna receives her Imaginary Friend.
LifeSimmer originally planned for Snuggles to be Male and to date Luna. However, upon learning that Snuggles is Female, LifeSimmer stated that she may be more like a sister to Luna; this is probably because she wanted Luna to start her own generation.
Young Adult Luna gets to work with the chemistry table, trying to make Snuggles's potion as a Love Day tribute, and finally turns Snuggles Human in Part 42. Due to the fact that she is the same age as Luna, Snuggles graduates High School with a Grade C - the default grade when a Sim begins school - despite never having attended. She remains part of the active household for the remainder of the Season 1.
Snuggles appears as part of an inactive household with the Fenderson family, sans Penelope and Jai. She attends Kendra's birthday party Part 4. She is seen at Penelope and Zane's birthday in Part 43. Snuggles is an Elder by the end of the season.
