+    yeah, the _move, _draw, _ct, _dt, and _save funcs all take ACTOR*, GAME*
+    thankfully the ZZZ_Profile data objects give us the class size, just re-type it to ACTOR_PROFILE
+Roeming — Today at 10:55 AM
+    hmm, not sure I understand
+Cuyler — Today at 10:55 AM
+    so AC is a weird pseudo-inheritance class system since it's C
+    all classes which inherit from ACTOR have an "actor profile"
+    which is basically like a weird C++ vtable
+
+    There will be data with this C file `ACTOR_PROFILE Museum_Fish_Profile;`
+    and part of that data will be the size of our UNK_FISH_STRUCT,
+    `Museum_Fish_Profile->class_size;`
