It's Green Treasure Hunters turn and before their turn they only have 2 available dice. Hence the Green Treasure Hunter decides to Reset the Dice.
As a result, the Mummy player performs an Interrupting Turn. After the Interrupting Turn ends, the Green Treasure Hunter rolls all 5 of the Treasure Hunters dice.
The roll results in - a Mummy Head, an Arrow, a 1, a 2 and a 3. Green Treasure Hunter is satisfied with their roll and chooses to use an Arrow for his movement. However, one die (with a Mummy Head) is set aside again.
