A Toughy! Test your inner logic!

You are walking in a strange cave and you have no idea where you are or how you got here. As you are walking, you come across some tiles on the floor. They read "AHOY DYE FOOT." Strange.

You pass a second group of tiles which doesn't make much sense. The third pile says "LUG TUNA BLUBBER". You wonder where you would find tuna blubber in this cave, and where you should lug it to.

At that point, you look further down the cave and see that there are many groups of tiles.

How many groups of tiles are there?


Anyone know it???
