Using the new route, I started making this TAS. I don't know how to get the Growl fails, but it is going to be less than 32 minutes if everything goes smoothly.
It would be greatly appreciated. I could do the text boxes with fastest text speed, and I've been thinking about whether or not the cooltrainer should be done by Pallet or in the cave. Here is my idea of the route (similar to the route on speedrun.com)
