The Dippy Dogbane is a Special Seed in Moshi Monsters, that attracts McNulty the Undercover YapYap. A code for the seed can be found in certain packets of Moshling Madness on the McNulty code card. The codes can be used once per person meaning that if someone dug up the seed, they would have to get McNulty by planting his seed combination or by getting another Dippy Dogbane. The seed must be planted with two other normal seeds in the Moshling Garden, when the seed has grown, McNulty will come.
