"Sparkle Pupa" could refer to a few different things depending on the context. Here are some possibilities:

1. Pokémon (Fidough/Dachsbun)

In Pokémon Scarlet and Violet, Fidough (a Fairy-type puppy Pokémon) evolves into Dachsbun.
During evolution, the Pokémon briefly takes on a sparkling, cocoon-like form, which fans might colloquially call a "Sparkle Pupa" (though this isn't an official term).

2. Original Character (OC) or Fan Creation

It might be a name for a custom creature, character, or concept in art, games, or stories—possibly a sparkling/metamorphic creature (e.g., a glittery chrysalis stage).
Could be tied to My Little Pony, Bugsnax, or other whimsical franchises.

3. Glittery Insect Pupa

A literal interpretation: a fictional or artistic take on a "sparkling" insect pupa (like a butterfly cocoon covered in glitter or magic).

4. Music or Media

Could be a song title, album, or reference from a niche game/show (e.g., Hollow Knight mods, indie RPGs).

If you meant something specific (like a game item or OC lore), feel free to clarify! I’d love to help dig deeper. ✨
