Please help i need it

It's hard, from your query, to tell exactly what you mean by 'cool guy' but I assume you mean you want your character to look good or at least to look the way you want it to.

When you talk to Kapp'n in the taxi on your way to your new town, you need to answer a few questions... Your appearance depends on how you answer these questions (so does your town's appearance) You could do one of two things.

1. You could find a guide on this very website in either the cheats section, the walkthrough section or the hints section for this particular game. (there is one there at least!)

2. You could answer the questions, see what you get and if you don't like that, turn the game off before saving or just start a new game and answer the questions differently and keep doing this untill you get a 'cool guy'

Cheers!

Jackieboy Tips:

Depends what you mean by cool.

If you want a cool hairstyle, you need to upgrade Nook's Cranny to Nookington's.
If you want cool clothes/accessories, buy some from Able Sisters or design your own umbrella/hat/shirt.

If you depends if mean cool guy by Animals or cool guy by your character.
If you want a cool animal then just want some and animals will move out and some will move in.If you mean by your character it depends on how your character looks by the way you answer the questions at the begining. You
Can also change your hairstyle at nookintons or buy different clothes at the
Clothe store.

If you go on youtube and go to "Animal Crossing Face Guide" you will find a bunch of faces to choose from and you can choose from there! It's quite easy. Good Luck


Hope I helped!
