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 floor[UK].
