First up, you may need us to refresh your memories about who exactly Reptar is. You might remember that Tommy Pickles and the rest of the Rugrats kids loved him and always had Reptar merchandise in the show. He was a t-rex, kind of Godzilla looking, and it seemed like the kids always had Reptar-branded everything, including cereal. Knowing this, it may surprise you that Busta Rhymes was the voice of Reptar in one Rugrats episode.
Not only that, he went back for more and played Reptar again in The Rugrats Movie. The reason this is surprising is because Busta Rhymes is a massively famous hip-hop artist that you wouldn't expect to be working on Rugrats. We love that he did it, though, and we're sure we're not the only ones who feel this way.
