Geckos! is a members-only music den item. It was released on April 27, 2017, and is sold in the Diamond Shop.
The cover art shows a red-bodied and pale green-underbellied gecko on a hill surrounded by trees. Beams of sunlight are in the sky. Above the gecko is a quarter note and an eighth note.
The song's melody is based on Jacques Offenbach's "Infernal Galop" from the Orpheus in the Underworld opera. It goes at a very fast upbeat tone, and a pitched trumpet can be heard in the background at many parts in the song. A voice rapidly repeats "gecko" throughout the entire song, and in the middle, it features fun facts about geckos. The song gets progressively louder, eventually coming to a crescendo, as more and more voices (made comically high pitched) are added on.
- This music is from one of Sarepia Theater's oldest videos called "Geckos!" that was introduced on October 1, 2010.
- The music video was removed for a while due to it containing the National Geographic logo, but it was updated with new visuals but the same music on June 7, 2018.
- This is the first den music to be based on an Animal Jam video.
- This is also the first and only den music to have specific lyrics in it; however, there are some music tracks (such as Jammer Anthem) that also include voices.
