He noticed a brown bear up a tree nearby. "Mom, there's a bear over there!" Sam called. "What if it comes down and attacks us?" asked Sam's little sister Sarah. Mrs. Miller took Sarah's hand. "We'll keep a safe distance away" she replied. "We need to get the bear down before our yard sale starts" Sam said. "We could always cancel the yard sale," Mrs. Miller said. "I put up so many signs," Sam groaned. I know we can get the bear to come down if we just brainstorm the right idea." "Like the idea you had for the squirrels?" his mom asked. Two weeks before, Sam tried to stop the squirrels from eating all the birdseed. He dug a pit around the bird feeder and ruined his mother's tulips. "This is different," Sam said. "I promised you I'd draw all my ideas first before I actually do anything." "We could move our trampoline under the tree so the bear could jump onto it," Sarah suggested. Sam drew the idea on his notepad. He pictured the bear bouncing high into the air. "I think the trampoline's too bouncy, Sarah," he said. "Mom, what would you do to get the bear out of the tree?" Sarah asked. "I'd play a really bad song from the radio," Mrs. Miller laughed. Sam drew the idea on his notepad. He imagined the bear climbing even higher in the tree to get away from the noise. "If you play a bad song the bear will never come down," Sam sighed. "Look, the bear's eating something up there," Sarah said. "He's probably found some nuts that were stashed away by squirrels," Mrs. Miller said. "I've got it!" Sam shouted. He scribbled his plan in the notepad and showed Sarah and his mom. "We can make a trail of nuts leading back to the forest," Sam said. "Let's get nuts!" Sarah yelled. "All right, let's try it," Mrs. Miller said. Everyone raced to the chestnut tree in the backyard. "We're going to get that bear out of the tree!" Sam shouted. While they were gathering the chestnuts, the bear climbed down from the tree. Sam returned just in time to see the bear disappear into the woods behind the neighbors' house. "Aw, the bear is gone!" he said. "Look on the bright side," Mrs. Miller said. "At least you can have the yard sale now," she smiled.
