Explosive Combination

Description
'' This...You have the plans for the fortress? Incredible! I can show you the weak points in its design. With a few well-placed bombs, we can tear through it like wt paper. We'll need to produce some explosives of course, but that shouldn't be a problem. You bring me the parts, and I'll assemble the bombs!''

''The pelicans collect all sorts of bits and pieces, and they snapped up the parts I need. I'm sure you can wrestle them away from those overgrown pests. Hurry!''
