Staff at Tesco in Market Rasen are going all out for fundraising this week.
Rio de Tesco runs to Saturday, August 13, raising money for their nominated charities - the British Heart Foundation and Diabetes UK.
Staff will be getting into the carnival spirit by wearing green and yellow, the Brazilian football team colours, and there will be lots going on.
Saturday will see a hula hoop competition, as well as face painting.
There will also be the opportunity to indulge in smoothies and popcorn.
Throughout the event there will also be a scratchcard raffle and lucky straw games, with an exotic animal visiting on Friday too.
