Mouse's First Spring

One bright day, Mouse and Momma head outside to play.
The wind blows in something
feathery and plump --
a bird,
and something
wiggly and pink --
a worm,
and something
green, who hops and leaps --
a frog.
But before it's time to go back inside, Mouse finds something that's
soft and new with petals...
the prettiest flower he's ever seen
Could it mean spring is finally here?
