  • Very good episode in my book for a season 1 finale.

    In this episode the DLCFDTL use the age changing cigar they got in the last scene of Operation C.A.B.L.E.-T.V. and they use this cigar to change Numbuh 1 into an adult. The DLCFDTL attack the tree-house and destroy it and change poor Numbuh 1 into an adult so he can't be a kids next door operative anymore. The KND go for ice scream to find there old leader Numbuh 1 selling ice scream. Numbuh 5 tell's Numbuh 1 he should help them out since he is still a kid at heart. All and all a good 23 minute episode for the last episode of season 1.moreless
  • Good!

    The Delightful Children From Down the Lane make it so that Nigel is transformed into an adult. This nearly destroys the rest of his sector, who decide to try and fix things. This leads to a fight between them and their most powerful enemy- Father. In the end Numbah One and his teammates win and Numbah one is back to being a kid.

    Great episode, it has a more serious tone then others and I think it was handled well. My favorite of the first season, my overall grade for this episode is an easy A+, just perfect I thinkmoreless
