Max and Lily weren't normal by any means. They were fearless and prepared for the jump.
Without any hesitation, Lily stood on Max's shoulders. This alone made them closer to the key. Just around 30 centimeters more. A short jump would do the trick.
"Are you ready, Lily?"
"Un, anytime."
Max let go of Lily's legs and she jumped. It was enough to reach one of the keys and grab it. The momentum died down at that moment and she fell.
Fortunately, Max was ready below her. He caught her gently in a princess carry and they smiled at each other.
"Got it."
"Nice."
She giggled happily as he set her down.
"Alright, now that we get it, let's move to the next test." Max said and walked away.
"Wait!"
Obviously, Queeny was the one who yelled. She even extended her hand and caught Lily's hand to prevent her from walking away.
"What about our key? What will you do about that?"
