+# Clams Don't Dance
+
+### Description
+Find the clam and open it to find the pearl. 
+
+### Suggested Point Value
+100
+
+### Solution
+
+A deleted file can be recovered from the image, `clam.pptx` with Autopsy.
+
+Unzipping the clam, there is an `image0.gif` inside of `ppt/media` that is MaxiCode for the flag.
+
+### Flag
+
+`flag{TH1NK ABOUT 1T B1LL. 1F U D13D, WOULD ANY1 CARE??}`
