Setting out on a foraging expedition in your local 'pick-your-own-creepy-crawlies' cavern, you discover that it is impossible to move on to the next chamber until all the glow bugs have been supped. You are equipped with ane elephant's trunk as a vital part of your anatomy. This acts like a vaccum, sucking up everything within range of its visible vortex. The blue glow bugs are ok but should they turn red they must be spat out immediately, but brown is fine as this gives temporary immunity against attack from the indigenous nasties.
Some of these said creatures, big bugs and birds, hatch from the eggs on the floor, while spiders drop in, creepers perform as their name suggests and the odd snake will slither after you. Unlike your staple diet, these creatures are lethal to the touch and should only be approached behind the cover of your vortext, even then they should be immediately regurgitated if they turn red. There are also some mega-loathesome beings which are totally taboo, along with the sometimes invisible phantom. If you make a meal of slurping your food, an earthquake may catch you short, sending down a shower of stalactites.
All the necessary, uncomplicated info is contained in a special instruction screen, which is as it should be in my book. Fanfares, drinking-your-tea-from-the-saucer slurping sounds and whistling winds add to the enjoyment: no jibes at the graphics called for either. Love it.
