Once you're finished exploring the aquarium, go back down the hill to find a path that leads to the Lollercoaster. Click on the sign to call a car, and don't forget to go into mouselook for a realistic ride!
The park contains several fun rides besides the Lollercoaster, including a bouncy castle, a ferris wheel, a merry go round, bumper cars, a parachute jump and a teacup ride. There is a small penny arcade with fortune telling machines and two very cool mutoscopes: "The Box" and "Le Train". Visitors can enjoy 7Seas fishing with custom prizes from any of the piers, or grab a free balloon from the booths that line Rte. 66. Along the shore of the Davis Gulf there are inner tubes you can float in, and maybe you'll even spot Jonah the whale in the water!
So what's with the hippos, anyway? Apparently, hippos are the unofficial mascot of Second Life, and can be found in many places all over the Grid. There is a giant underwater hippo statue in the Mare Secundus, a much smaller statue in the Second Life Historical Museum, and there is even a hippo easter egg in SL browsers (press CTRL, ALT, SHIFT then hit the H key). Apparently, to see a group of hippopotamuses in your dream suggests that you need to escape from the daily grind and relax. (Shouldn't that be "hippopotami"?) So escape your daily grind, bring along a friend or two, and relax at Hairy Hippo Fun Land!
