Wally the walrus causing havoc among boat owners

Wally the wandering Walrus has been causing a stir again - this time by trying to find a place to have a nap.

The huge mammal was first spotted off the coast of Ireland earlier this year, before going on to become a local celebrity after a brief stay in Tenby and later making appearances in France and Spain.

The latest stop on Wally's whistlestop tour of Europe is the Isles of Scilly, an archipelago of 140 islands about 40 kilometres off the coast of Cornwall, where he has been getting friendly with the locals and hauling his massive bulk onto boats.

Some of his attempts have been more successful than others, however.

One standoff with a boat owner in St Mary's harbour, in the most populated of the five inhabited islands in the Isles of Scilly, ended with the man looking somewhat defeated by Wally's efforts to flop himself into a dinghy tethered to his boat.

Some people have been a little happier to see Wally, however, with a group of tourists thrilled to see his efforts to join them on a boat trip recently.

Wally arrived in Porthcressa Bay on June 17 and, after spending a couple of days feeding around St Martin's island last week, spent two days dozing on a small inflatable boat in St Mary's. Joe Pender, who runs boat trips around the islands, took the opportunity to take photographs of Wally's latest escapades.

"I run a passenger boat around the island for tourists doing wildlife trips and trips to the other islands.

"I received a call saying Wally was trying to board some boats, I was heading out on a trip so-called in and took my first photos of him. On Thursday, he was found asleep in a RIB (rigid inflatable boat) in St Mary’s harbour, which he spent two days in.

"He then went back to St Martin's until yesterday (Saturday, June 26) lunchtime. when he came back into the harbour trying various boats to haul out on capsizing some".

He also tested the comfort of an ambulance boat (Robin Mawer)

The images show Wally trying a few different boats for size, on one he appears to be struggling to squeeze his huge body onto the vessel, in another he seems more content and relaxed as he snoozes away the day.

Wally is thought to have drifted from the arctic on an iceberg and experts hope he will eventually make his way back to his icy home.

For now, though, it looks like he's quite happy where he is.
