"Sisters Elsie and Theo are at recess one day when they see a nut wiggling on the ground. When they gently crack the shell, out pops Benny--the world's smallest, chattiest, and most gentlemanly walrus. When Benny tells the girls that he misses his home in the sea, they build him a milk-carton boat, and send Benny sailing, along with an adventurous band of three slugs. Together, Benny's Brigade (as they call themselves) begin an adventure to a truck-sized island paradise, avoiding the salt water as much as they can. Slugs don't like salt."
"After prying open a strange nut wiggling on the ground, sisters, Elsie and Theo find a miniature walrus named Benny inside, who accompanies them to school where the girls and their classmates build him a boat to sail home on."
