Can you find 'Dolcasso' the roaming dolphin?
As part of Hospice's Big Splash campaign, one of the sculptures will be placed in a different location every Friday until September 19.
'Dolcasso' doesn't feature on the main trail with the other sculptures, and so doesn't have a code or feature on the Big Splash app.
However, there is a stamp for the wandering dolphin in the printed passport and trail goers can win a t-shirt by sending a selfie with him to marketing@iomtoday.co.im
