Mia, Matt and the Lazy Gator (Formac First Novels)

Twins Mia and Matt can't wait to get to their uncle's summer cottage and find out what animal will be the star of their vacation. Uncle Orlando is the best animal trainer in the country for movies and television. Last time, they helped him train a group of pigs to sing.
This year turns out to be a challenge—to get an alligator, the slowest and laziest animal on the planet, to dance! All Nestor the Gator will do for Orlando is bathe in the sun. Will the twins get bitten, or will Matt's breakdancing skills help Nestor learn some moves?
Suddenly, a strange thing happens--the gator starts making a sculpture out of mud and grass. What is he up to? Mia and Matt are in for a surprise! The alligator turns out to be female, and soon thirty baby alligators, nesting in the sculpture, hatch from their eggs.
