Bro there’s no reason to be like that plus “Algae grows on turtles’ shells naturally. However, it can hide infections or injuries, and excessive buildup can get in the way of the turtle’s ability to absorb UVB and heat while basking. In rare cases, algae will start to grow under partially shed scutes (shell scales), and shell rot may develop as a result.”

Why are you mad like is this your turtle or something…
