After being spotted earlier this month in Kerry coastal waters, Clet – the French cetacean interloper first seen in West Cork – was thought to be headed towards Fungie's usual haunt around Dingle.
But in recent days he's been spotted off Inis Oírr in the Aran Islands, frolicking with another recent resident of that island.
Sandy is perhaps better known to Afloat.ie readers as Dusty, the Doolin dolphin that was the subject of much controversy last summer after a number of aggressive acts against swimmers, one of whom was hospitalised with serious injuries.
And now with Clet's arrival, it seems these two dolphins with bad reputations have made the perfect couple, with the Irish Whale and Dolphin Group saying Clet has "hit it right off" with Sandy.
Still, the IWDG has reiterated its warning to swimmers and other water users to stay clear of the pair based on their track record.
In other cetacean news, the Irish Examiner reports on a rare sighting of killer whales off the south-west coast recently.
The seven-strong orca pod was spotted in the Atlantic near the Porcupine Seablight by researchers on the IWDG's Cetaceans of the Frontier Survey cruise on board the RV Celtic Explorer.
Joe.ie has images of the killer whales, which are common to North Atlantic waters but rarely trouble Irish shores; the last significant sighting here was a different orca family in Lough Swilly visiting from Scotland, and believed to be on the 'brink of extinction'.
Elsewhere, BBC News has footage of a large dolphin pod swimming close to the shore in Portrush on the North Coast, in what's described as a "very unusual" occurrence.
And here's a link to last night's RTE television programme on basking sharks.
