For the people out there who are stuck here is what i got for the 100% achievement:
All bike and go kart races
All rubber bands and G&G cards also smashed all Gnomes
334 clothing ( if u are stuck buy everything in the carnival tent except the scooter thats what i had to do).
That is just some of the things u have to do, but i listed those above because people keep asking how many clothes do u have to get and how many errands u have to complete, well that above is what i did, hope it helps
