Baby geckos are hunter creatures that may be caught with level 27 Hunter and level 10 Summoning. They are caught using box traps, which do not need to be baited. They come in four different colours, which may be found in different locations across Karamja. Adult geckos can also be found, but these cannot be caught.
Once caught, players may loot the trap to receive a baby geckopet. If a player already has a gecko, the trap will always fail to work, unless the gecko is in the menagerie.
