I hope this is an iceberg lettuce! Inuka the polar bear tucks into a meal at his 'house-warming' party at Singapore Zoo The 22-year-old has moved into a new £5million home named Frozen Tundra Specially-built enclosure four times bigger than previous one Includes giant pool with ice blocks, waterfall and cave for sleeping First polar bear born in the tropics in captivity in 1990 Moving home is usually a stressful experience, but Inuka the polar bear looks like he is having no problem chilling out in his new £5million arctic enclosure. The 22-year-old, who was the first bear of his species to be born in the tropics, has been moved into a specially-built, climate-controlled home at Singapore Zoo named Frozen Tundra. The 2,700 square metre exhibit features a huge pool with giant ice blocks for him to rest on while swimming, a waterfall and an ice cave for him to sleep in at night. Lunchtime: Inuka the polar bear tucks into some greenery as he moves into his new enclosure in Singapore Zoo Varied diet: Inuka tucks into a frozen block of fruit and fish as he celebrates moving into his £5million new home Designer home: Singapore Zoo says the new enclosure has been specially-built to mimic the polar bear's natural environment as closely as possible Unique: Inuka was the first polar bear to be born in the tropics when he arrived at the zoo in 1990 Refurbishment: The 2,700 square metre exhibit features climate- controlled resting areas and an expanded pool Singapore Zoo say the enclosure, which is four times bigger than the previous one, has been modelled as closely as possible on the polar bear's natural habitat. The organisation has been planning a new home for Inuka since 2006 and has spent millions on the upgrade. Natural substrates have been incorporated to provide him with a rich and varied home. It also has two new sections for Inuka's new neighbours - raccoon dogs and wolverines. At Singapore Zoo, we remain committed to not only providing a fun and beautiful park where families can bond over the wonders of mother nature, but also to our vision of engaging and educating our visitors about the natural world, the animals that share our planet and their habitats. This is a core value of Singapore Zoo,' said Mr Lee Meng Tat, CEO, at Wildlife Reserves Singapore. Those values and goals go hand in hand with our deep love of our animal friends here at Singapore Zoo, and Inuka is a shining example of that love.
