I don’t mind answering stuff again. I have over 3000 blog posts on my Tumblr blog; I can’t expect anyone to read it all before interacting with me ^^. Also, years have gone by; I live and learn! My answers to similar questions may change from year to year as I learn about new things and go through difficult and fun activities! Stagnating your own development or solidifying your opinions too much is probably not a good thing.
The shark plush is BLÅHAJ from ikea. They have the large 1 meter one, which I have, and two smaller versions. You can either get it directly from them, or through a bunch of resellers on online shopping platforms ^^. Though, there are also similar shark plushies for sale. Supposedly, there are also larger shark plushies which were created based on blahaj, but I find them too expensive ^^;;
