Mud! is an energetic picture book ode to rainy days, outdoor play, and siblings, all about oozy, smoozy, squishy mud! Gloopy, gloppy, gorgeous mud. Ooozy, smoozy, soupy mud. Stomp it, poke it, squeeze it, whack it, Pack it into bricks and stack it. This very young picture book from author Annie Bailey and illustrator Jen Corace celebrates all things mud! The rhyming text is full of onomatopoeia and humor and follows a brother and sister as they go outside on a rainy day to play in the mud and then clean up—only for the muddy fun to start up again. "Young readers who love to play outdoors and funky onomatopoeia will freely revel in this story of messy fun." —School Library Journal
