Great video, thanks for taking us through the aquariums! On your question about talking speed, I thought it was the perfect speed and it was really calming to listen to.
I live in the Netherlands, so been to the Netherlands sealife animal crossing event. It was a bit underwhelming. We did a stamp rally trough the aquarium and we could find letters from blathers where you could make a word from. Didn’t get all so don’t know what the word is. We also found gulliver and we went on a photo with a reallife tom nook. The giftshop had only 3 plushies, some Lego sets and an aqua beats set, so nothing like you have from Japan. It was fun, but won’t do it again
