The tree diagram would have a separate branch for each outcome of the spinner. From each of these branches there would 6 branches representing the numbers 0 to 5. If the spinner had 3 outcomes, there would be 3*6=18 possible outcomes, and if the spinner had 6 outcomes, the combination would be 36 possible outcomes. There would therefore be 18 or 36 "leaves". Any one of these could come up in the first and subsequent spin and roll.
