Collecting swamp toads
544 × Swamp toad (1,583,584)
Swamp toads can be picked up at the swamp northwest of the Grand Tree in the Tree Gnome Stronghold. There are 18 spawns, and it takes approximately 45 seconds for one to respawn on a high-populated world. Because of this, you will have to wait a few seconds after picking up all the toads before you can go through and pick them up again. After you have a full inventory, run east into the Grand Tree and southeast to the central tree with a ladder. There are two banks on the western part of the 1st floor[UK]2nd floor[US].
Toad's legs can be made by clicking on the swamp toads in your inventory, yielding 1,199,100 per hour. The legs can be quickly pulled off on the run from the swamp to the bank. This usually lowers the value, so be sure to check the prices of both. Currently legs are worth 1,713 while the swamp toad itself is 2,911.
