They are on a mission.

Not sure what they think is under or behind this rock, but they dug & dug this afternoon. Never stopped until I dragged them away from it.
I have finished the photobook for L, and ordered it online, so decided there wasn't much else to do, so went out to trackle the weeds in the garden.
Gypsy & Poppy decided it was a good thing to go through the grass looking for something, then they decided to dig behind this rock. Then one of them started from the top too.
