Playmobil 71531 - Pirate Treasure Island and Sea Monster

Includes two characters, an island with vegetation, a boat and a treasure. 
The island is well protected against pirates: upon opening the entrance, the island's crystal eyes disappear, revealing two cannons ready to fire...    Which brave adventurers will dare to venture onto the mysterious PLAYMOBIL treasure island? 
It is said that a precious treasure is hidden there. 
However, those who want gold and crystals must first get past the lightning-fast sea monster. 
And that's not the only obstacle as the treasure chest is located in a spooky skull cave, secured by working cannons. 
But a real pirate cannot be stopped by any danger.
