Toot is an eager and energetic tug in his first year of service. Under the watchful eye of Lenny the Lighthouse and his special cast of friends, Toot's job is to lead big boats into the harbour and rescue ships in distress. However, sometimes Toot is prone to mistakes and neglects his duties in favour of fun. Luckily, he learns very quickly and is always keen to get back on board with his cheerful shout of 'Heave-ho, let's go!'
