How can I mak my walmart bmx bike better?

Ok I know that walmart isnt the best choice to buy a bmx bike, but I was on a budget and was forced to buy one from walmart.Please take a look at walmart.com at the bike called Thruster Chaos BMX bike and tell me what I should remove and add.The parts I already took off were the front pegs,chain guard, all the stickers lowered the seat all the way down and I am looking for a tool that can take off my kickstand.
