1990s Spiderman Cartoon Question?

i'm trying to kind the episode where spiderman takes on the fantastic 4. i cant find any info on it any where. i own the entire series and cant find it. i'm just wondering if i'm on crack, or if it was a special episode, or what. i'm not talking about where he goes the the other planet with the F4, storm, capt america, and iron man. this was totally differnt.

i remember spiderman going to the fantastic 4 for help. they end up fighting and spiderman ends up winning until mr.fantastic gets in the way and talks to spiderman. thats all i remember, if you can help me find this episode, or hell even if you remember seeing it.

thanks
