我在岛上所遇到过许多生物，但还没有哪一种可以像禽龙一样可以根据需要改变其运动方式。 禽龙通常都是懒散的两足行走。在岛上许多草原和森林中能够找到它。然而在需要速度或机动性的情况下，它可以快速地切换至四足姿态，表现截然不同！ 虽然是双足动物，它可以用其独特的拇指尖快速突刺。相反在四足形态下，即使在冲刺时似乎也要无穷无尽的耐力！
Common name: Iguanodon
Species: Iguanodon vicissitudinis
Time: Late Jurassic
Of the many creatures I've yet encountered on the Island, the Iguanodon vicissitudinis has the distinctly versatile capability of switching its primary method of locomotion according to its momentary needs. Primarily a rather lethargic bipedal herbivore native to the Island's many grasslands and forests, in situations where increased speed or maneuverability is called for, it will quickly shift its posture into quadrupedal stance and behave like a very different creature! While bipedal, it can employ rapid, stabbing attacks with its distinctive thumb spikes. In quadrupedal stance, conversely, it seems to have an endless supply of stamina, even while sprinting!
Interestingly, the Iguanodon's thumb spikes also provide it with the capability to pick seeds out of fruits, allowing a farmer to easily convert stacks of fruits into stacks of seed for planting. Combined with its highly effective fruit harvesting and substantial carry weight, the Iguanodon's excellent mobility in bipedal stance makes it an ideal field-hand that can also pull off a quick get-away or an agile defense when needed.
