This is a serious post. I looked at the Rugrats game Wikipedia page where they list names of the games about a Rugrats or that have Rugrats in them and one of them was Rugrats Food Fight from 2005. I love Rugrats and I wanted to play that game so I went to the App Store, (it was a mobile game), and searched for Rugrats Food Fight. Nothing came up. So, I searched online, YouTube, Google, etc., nothing came up. The description of the game reads, “It's a lunchtime meatbrawl! Your favorite Rugrats may be all grown up, but they know a good food fight when they see one. Choose Chuckie, Angelica, or Tommy, grab some grub, and get ready to dodge donuts, plaster pizza, and catapult some cake in this messy splat-for-all! You've gotta get your friends before they get you.” It says the game was developed by Mobblis. I searched the web for that and nothing came up. It’s supposed to take place in the All Grown Up Rugrats series. Please help me find this lost game!
Seeing as the game came out some time between 2005-2007 it's safe to say this is a pre-smartphone game. It was never on any modern app stores. This makes it harder to find. Not impossible, just harder.
The pre-smartphone era was a weird time. Games often only came out for certain service providers and sometimes only specific phones. One of the most notorious examples of this being Kingdom Hearts: V-Cast (https://lostmediawiki.com/Kingdom_Hearts:_V_Cast_(partially_found_mobile_game;_2005))
Mobliss games were available on all major US carriers according to this Wikipedia article (discusses a Burger King mobile game towards the bottom): en.wikipedia.org/wiki/The_Burger_King
That's a good sign.
If anyone here had it on an old phone back in the day, that would be the easiest way to acquire it.
