Spawning from large, organic globules (Giggi Sacs) in dark caves, they exhibit unique behavior.
When the torch is drawn, they retreat in fear; however, when the torch is extinguished, they slowly follow hunters and latch onto them, constantly draining "blood", doing damage similar to the poison effect, and must be "shaken" off. If a Giggi sucks a significant amount of health off the victim, it will be able to do a poison spit.
- As a Giggi sucks the hunter's blood, it starts to increase in size, but will only reach a certain body mass.
- Giggi can be found in every environment in Monster Hunter 3, but its adult form, Gigginox, can only be found in the Tundra.
- Despite not having wings or legs, Giggi are still classified as Flying Wyverns.
- If a Giggi is not shaken off it may inflict the hunter with poison.
- When hit twice with a torch, Giggi will flee by hiding underground.
- Before flying at a hunter, Giggi will scrunge up for a few seconds. This is a good warning. At this point, the hunter can move and Giggi won't reaim.
- In Monster Hunter Diary, Giggi are found in the Khezu-Quest, while there is no Gigginox in the Game.
- If a Giggi is attached to a hunter, Cha-Cha or Kayamba may attack the hunter to get the Giggi off.
- If a Giggi Sac is present, but no Gigginox, the Giggi will attack Baggi to defend the sac.
- Gigi (giggi) in Indonesian means tooth.
- Giggi are the only small monsters in the Flying Wyvern family.
- Giggi are the only monster to inflict the new Life Drain status. To cancel this, just roll/dodge 1 to 4 times to have Giggi fall off.
