A Crucial Item

This item is crucial. Congratulations on defeating Chimpy. The battle may have been fierce, but you persevered, and Chimpy has left you with his final blessing. Chimpy faces his honorable death like a true warrior, and does not try to bargain like a coward. Chimpy's memory lives with you now, and he lives with you in spirit. What could this final gift mean though? Perhaps one day Chimpy will prove his worth one final time, and its purpose will be revealed.
