Use an ogre bellows which has been loaded with swamp gas on a swamp toad to get a bloated toad which is placed in the inventory. Only three toads may be obtained at one time. Attempting to get a fourth toad gives the message: "One of your bloated toads manage to escape. You manage to catch the toad and inflate it with the swamp gas."
Bloated toads may be dropped in the ogre area in Feldip hills (north of the hunter area). Players attempting to drop them elsewhere are told "You won't attract a chompy bird this far away from the ogre area". Once dropped, they have a chance of causing a chompy bird to land. They will eventually explode, and the blast used to cause minor injury to a player standing near the exploding toad.
They may be released from your inventory, doing so will result in your player character saying ingame "Free the fat toadsies!" (Fat Toadsies being in reference to name Rantz calls the toads by during the quest) and then all of the toads in your inventory will be removed despite only having to click release on one toad.
Using Ogre Bellows with swamp gas in them on a bloated toad in the inventory will cause a hilarious animation to ensue.
