Leto gasped in delight when her eyes adjusted to see the fuzzy thing in her father's mouth. That was the present?! It was so FLUFFY AND AMAZING she just wanted to KILL IT AND RIP IT TO SHREDS!! But her jaw dropped in comedic horror as he sent it sailing away with the added admonition that they had to be the first to bring it back. "Whaaaaaaat?! No fair no fair!" she squalled as her larger sister took off. Arry was so much bigger, she always won races! Welll..... she always won fair and square races but did Daddy say it had to be fair-and-square? Why no he did not! She threw herself forward on the very heels of Arry's own exit, her own shorter-and-stubbier limbs a blur of even blurrier color that could not hope to bring her in front of Arry... but she was not aiming to get in front of her younger sister, nope! Instead, she had to be sneaky! The little monster wanted to sink sharp little baby monster teeth into her sister's tail and jerk backwards until she stopped, but Arry was bigger enough that she'd probably just drag Leto along like a burr until she got to the rabbit and won anyway... So instead - with a wild shrieking war cry - she flung her whole body on top of her sister's back in an attempt to tackle her to the ground, slobber all over her face (she was ready with a mouthful of slobber pooled on her tongue already waiting to drool all over Arry's face), and leap off again to victory! Or at least... that's how she pictured it happening...
