During the second season, they attempted to discover the secret identities of the Power Rangers and repeatedly failed either due to their bumbling nature, or the Rangers' interference. The duo eventually give up by the time of the episode "A Friend in Need: Part III". During this time, Bulk and Skull started showing greater intelligence and initiative than before, coming up with complicated plans and utilizing bizarre gadgets. While a majority of their plans were hair-brained, a few of them were actually clever, like making a cement cast of the Power Rangers' footprints so they can see if any civilians' feet match. They discovered the Rangers' identities "twice". At one time, they saved the Rangers when the Ranger team lost their memories and de-morphed in front of them - Bulk and Skull tricked the Scatterbrain monster to fire his amnesia beam through two prisms, distorting the beam and restoring the Rangers' memories. Unfortunately, Bulk and Skull lost their short-term memories in the process due to being flung back by the amnesia beam and landing on their heads. The second time, a psychic pointed the Ranger teens out to Bulk, but he did not believe her as they were holding a picture of the morphed Ranger team at the time when it was just given to them by Ernie.
