Feel free to backpack these for usage in your own projects! No credit necessary. These two blocks are holdovers from Scratch 2.0, which had a dropdown with these two options which you could also type a number in. Instead of have an extra "item (random/last) of list" block, Scratch 3.0 kind of cheated and lets this particular "number" input also accept the words "random" or "last"... but only if you paste the word into the input all at once (or import them from 2.0 or your backpack).
