It's Raining, It's Pouring by Poppy Green

[Little Simon] Sophie Mouse and her furry friends prepare for a big storm that’s headed right for Silverlake Forest in this tenth charming book of The Adventures of Sophie Mouse series! Sophie Mouse has been preparing for the first-ever Silverlake Forest Spring Fling for weeks. She has come up with activities, like a Lily Pad Dance, she’s thought of games to play, and she’s created all sorts of fun hats, masks, and other costumes for her friends to wear. But the day of the Spring Fling is approaching, and Sophie’s twitching whiskers are telling her that the rain is too! Sure enough, it rains and it pours. Will Sophie figure out a way to save the day or will all her hard work go to down the drain? With easy-to-read language and illustrations on almost every page, the Adventures of Sophie Mouse chapter books are perfect for beginning readers.
