Ages 3 to 5 years. Twins Freddie and Teddy are Double Trouble on Halloween! Freddie as a gory goblin and Teddy as a one-eyed pirate create chaos as they gleefully scare their household. As they prepare to go trick-or-treating, mum asks them to remember to be polite when given a treat by the neighbours. However, the twins forget to say thank you for treats as they try to be as scary as possible. When they get to their Uncle Ernie's house, they get a scary surprise when a big gorilla jumps out at them! As their mother reminds them of their manners, they realise the gorilla is their uncle. They thank him for the candy he gives them, and then Ernie lets them try on his costume. This book shows children that being polite is nothing to be afraid of!
