    Sorry this took awhile. I've got 8 absolute banger videos I'm currently working on through April 2021 but it turns out the Rona slows things down a bit. They will be worth the wait! For updates, follow me on social stuff @MarkRober.

    I want to create the most evil puzzle a 10000 piece puzzle with no edge so pieces stick out and the colour is all the cardboard colour so it’s upside down and right side up and there is 500 extra pieces so you will mess up pieces try and put a right side up piece down side up without knowing the colour of each side and some pieces don’t fit because they don’t connect

    To be fair, that wasn't just fish blood it was blended whole fish, with that said, it's obvious that sharks will be attracted to raw smell of blended flesh... I think it would've been the same if you blend a chicken.
