My Little Pony Camp Bighoof #5

Campers, this is it! The entrance is clear, and everypony is ready to go home... after one last campfire! Plus, Sunny and Zipp finally have the evidence they need to prove Bighoof is real and become super famous investigators/scientists/camp counselors. But is there more to life than becoming an investi-sci-counselor-ist? Only Bighoof has the answer...which is unfortunate since she cant talk, but Im sure our investi-sci-counselor-ists can figure out what Graaahhh, grrr hrgh grah means in Bighoof!
