I liked the transformation, seems fun, but I would loved to see YL transform into a parody form of Capital B for the Cashino Level, some kind of Bee like character, allowing access to special staff-only rooms. A mediocre flying abilitie, Sting shooting, etc. That could be funny.
This transformation will definitely come in handy, and knowing Playtonic, there's most likely a pun involving the word 'ballistic' being made by either Laylee or Yooka.
A bee would be a fun transformation but they already did one in Cloud Cuckooland for Tooie so they may avoid it in YL (and maybe the possible sequel?). Who knows! I love the animal transformations the best
