Slap-Es are robotic minions of Dr. Cortex. They are small, weak, cylindrical robots that ride around in purple hands to increase their strength. They can attack, jump, block, and walk with their fingers. They are mainly found in the Space Head and they can be found everywhere else after Cortex has been defeated.
If a Slap-E cannot reach Crash, it may say "Error 404: Bandicoot not found", which is a refrence to the once common "Error 404: Page not found" error message found when a web page is missing.
If a Slap-E is killed by Crash, it might say "Curse you video games!" which breaks the Fourth Wall.
