This bag is constructed of heavy cloth. 

It is about 2-ft wide and 4-ft long (the size of any other bag or large sack). 

When it is opened and examined it will reveal several large pebble-like objects. If these objects are dumped out of the bag they will each explode for 5-20 hit points of damage each, all creatures within a 10-ft radius must save versus magic or take full damage. 

To be removed safely, the beans in the bag must be taken out by hand; telekinesis will not work, nor can they be worked out using tools in any way which will not explode them. 

Each pebble-like bean must be placed in dirt and watered. From each, in succession, will spring some creature or object. It is suggested that 3-12 beans are optimum, and only 1 or 2 will be beneficial, the others being monsters or useless things.
