Someone please for the love of god help me find this game. It has been bothering me for awhile that I haven't been able to find it. This is probably the first ever gaming memory I have. it was on either sega or nes. (Probably sega geneis) All I can remember from it was the intro. It was a bunch of little frogs with different colors hopping down a tunnel of rainbow cubes. Im starting to think it was really obscure because I looked through all the frogger games and the intro isn't in any frogger games so it is not frogger. I have no idea what it could be this is honestly the longest most interesting nostalgia search i've ever had. I don't care if it takes years to find this game it would be well worth it for memories. (Even though I only remember one part of the game)
good luck
