Is there a thing to do if bulbasaur doesnt have a 16 in the special stat after weedle guy, so you dont have to restart the run?

yes - you can do pp strats, which involve lowering bulbasaur's pp for tackle to 16 and his growl pp to 36, learning leech seed, and putting the moves in the following order - leech seed, tackle, growl. Also, be sure you dont go over level 8. Hopefully I didn't leave anything out.

thank you!
