Before Prof. K and Giana were dismissed, Rex asked about the result of the Honey Moon.
Nobody was available at the time so both of them had to be the one.
Rex instructed both of them—to gather the Lunar Bees from the other subservient kingdoms and use them—to find treasures. Considering that the Honey Moon was an anticipated event for the Werewolves, he couldn't afford to miss it.
If the Honey Moon passed, the Lunar Bees would disappear alongside it.
So Rex has to task someone to use the Lunar Bees.
Both of them were firm in their answer, they had used all of the Lunar Bees to the last one.
All of the gathered treasures have been stashed in the treasury.
However, what surprised Rex the most was the number—of Lunar Bees the other kingdoms had gathered. Based on Prof. K, the highest amount came from the Elves who had gathered a whopping 8 Lunar Bees followed by the Orcs and Dark Elves at 4 and 3 respectively.
