Extending Eye Lobes, or Eye Lobe Extension, is one of Bunsen's Powers. It is first used in Bunsen Is a Beast! (episode) and seems to be one of Bunsen's favorite powers as it is used in multiple episodes.
Bunsen uses Eye Removal (On Lobe) while extending the length of his eye lobes. He often uses this Power to see things above his head, Shape-shift, or just have have fun.
