I'm making a game where you click the scratch cat and it says something random. I'm using the list for the random words, and now I want a random explosion every time the scratch cat randomly says “explode” (the explode is also in the list). How do I do that?

Something like this would be what you're looking for:

when this sprite clicked
set [random v] to (item (pick random (1) to (length of [random words v] :: list)) of [random words v] :: list)
say (random) for (2) secs
if <(random) = [explode]> then
broadcast [explode v] 
end

The script above is for the Scratch Cat sprite. Then, under your explode broadcast, you can create your own explosion. If you need more help, let me know.

Thank you so much!!
