When the pigs took over / by Arthur Dorros ; illustrated by Diane Greenseid.

Enhanced descriptions from Syndetics:

Don Carlos wants more. "iMas! " he says. More! More of what? More of everything!he likes to wear more than one hat (sometimes ten at a time). He likes more than one flavour of ice cream. (He'll eat several cones at once.) But most of all, he likes to serve more at his restaurant, the only one in town. Everyone loves to eat his huge platters of food and listen to his little brother Alonzo's beautiful violin playing. One day, Don Carlos decides to add an extra dish to his menu, caracoles - snails! But he wants more snails, and mas, and iMAS! Unfortunately, the snails have their own dining plans, and soon the town is overrun by the pesky creatures. It is up to little Alonzo to save the day, but not before his big brother brings a lot more trouble to town. This is a riotous tale of two brothers - one small but enormously sensible, one big but a little crazy - told with the warmth and sprinkling of Spanish found in Arthur Dorros's other beloved, groundbreaking books, Abuela and Isla.
