Well, after you are done with every challenge, talk to Heather, Gwen, Justin, Beth, Leshawna, Geoff, Bridget, (you get it.) They'll say "Psst! Do you want to make an alliance" If you want to, press up, then z. If you don't want to, then press down, then z. But if you make an alliance with Gwen, she'll ask you to pull a prank on Heather, she'll get ticked, so you have to fight a bunch of spiders. But, you can only have an alliance with ONE person. If you disband your alliance, the former person will hate you. Give them a friendship bracelet from Chef's Vending Machine to make that person friend's with you. Hope this will be helpful!
