About Souvenir Auras

I received a question about auras, so I'm posting this in case some people haven't noticed. If you tap the souvenirs your cat brings back, you can open the details, and there's a section called Aura. There are souvenirs with nothing written in the Aura section and souvenirs with something written. Those with something written have a buff-like effect for playing the Cat Journey. Aura Types: ・Growth Boost → Catnip growth ・EXP Up → Contents of the bottle ・Coin Find Rate Up → Carry-back rate with souvenirs I believe this understanding is probably correct. Sorry if it's wrong.
