I remember owning an old Nickelodeon Magazine ad for SpaghettiOs featuring a real kids dressed as Dora the Explorer and Jimmy Neutron both enjoying a bowl SpaghettiOs. I unfortunately don't remember what year the magazine was from but I can certainly say it was somewhere in the mid 2000s, since thats when Dora the Explorer and Jimmy Neutron was still airing.
I really would like help finding this thing cause it's been in my head for along time and I have some fond memories with it.
