NUDIE Alert! 😍
Georgia noticed a tiny moving dot on the side of an aquarium yesterday, it was smaller than a piece of salt but moving quickly so we gently popped it in a container to take a look and its a tiny weeny Nudibranch 🤩
Upon further inspection we found another 4 so we are now researching what type they are, if you know or know a Nudibranch expert please let us know!
It has purple/ pink details.

Poor Evil Edna has eggs and the boys know it!
Watch them chase her around puffing out their pouches trying to compete to be her man and show her they can carry the most eggs 🥚 whoever she chooses will be getting her eggs to incubate and deliver in a few weeks!
Over the next few days if your visit look for these behaviours as she makes her way through the boys 😅

Were back!
We had a lovely time in Monkey Mia and Geraldton, lots of dolphins, turtles, hermit crabs and even a couple of Dugongs.

A shame we had to come back and deal with shoplifters 😭😭 as if extortionate rents, shire rates and wages arent killing small businesses as it is.

Massive thanks to Skye and Tiani for keeping our fish babies alive and well, its a huge job and they nailed it 👏
Were are back open tomorrow and look forward to seeing you ✨️ we have Busselton Monopoly available in store, a fresh restock of Miki Jewellery and a heap of brand new ocean themed books and jigsaws to unpack too 😀
