Tina the tortoise has been given a lift after being fitted with a suspension system and a pneumatic tyre to help her cope with muddy terrain.
The three-legged reptile can now go 'off-road' after the 4x4-style system was attached to her shell.
Tina was fitted with a plastic wheel four years ago to replace her rear right leg.
But our increasingly warmer autumns mean Tina hibernates later in the year, leaving her battling to cope with muddy grass and slopes and dead leaves.
So the rudimentary wheel has now been replaced with an air-filled tyre and a spring suspension system with shock absorber.
Speedy Tina can now explore areas of her enclosure at Longleat Safari Park, Wiltshire, which have been out of bounds to her in the past.
The spur thigh tortoise was donated to Longleat in 2002 when she seemed to be depressed because of her lack of manoeuvrability.
She rapidly recovered when the plastic wheel was fitted but it wore out and buckled over time as she tried to access rougher parts of her enclosure.
The new wheel and suspension system were made for Tina by model maker Simon England, from Frome, Somerset.
The large rubber wheel and adapted axle were stuck on to Tina's shell with an animal friendly adhesive.
Darren Beasley, the animal's carer at Longleat, said: 'The new system is incredible and allows Tina to go all over the place. She is one of the oldest tortoises we have here at Longleat but you would never know it. She is now among the fastest and certainly making the most of the warm weather prior to hibernating. And she can cope with any terrain – it's amazing.
