How To Teach a Bear to Meet the Queen
S1 E4:
Big Bear is worried. He's received an invitation to have tea with the Queen; he has been on plenty of picnics, but never tea... So Rosie and Raggles teach him 'going to tea' etiquette. Of course the invitation is a prank by Will... so Rosie and Raggles invite a disappointed Big Bear to have tea with them, which he does in style.
