Baby shower foods, games, etc...?

Never been to a baby shower so I have no idea what I am doing. It will be on the 31st of this month. So far as for food, we're gonna have 150 cookies, Krispy Kreme doughnuts, nacho chips, salsa and punch. Should I add anything else or just leave it be? Also looking for what else people do at baby showers such as games. Any suggestions? It is a jungle themed shower, the same as the baby room, any suggestions for decor, plates, cups, etc. And anything else you'd suggest or like to add. I have the shower invites finished and will be getting those printed next week also sent the majority through email. Thanks for all help.
