When clicked, the dog says "Meow!!!" as the "Woof!!!" bubble is shown first and then it is replaced by the "Meow!!!" bubble (see inside). As for @TheLogFather's project https://scratch.mit.edu/projects/18490761/, if I delete and recreate the "Woof!!!" script, the dog should say "Woof!!!" when it is clicked, as the first script created is run first and then the bubble is replaced by the "Woof!!!" bubble. But this doesn't happen: whatever script I create last the visible bubble is always the "Meow!!!" bubble. Instead, if I swap the two SAY blocks under the two WHEN CLICKED blocks, the bubble showing up each time changes. So, what is the real order of execution of the scripts of a single sprite?
