Smell Your Way Home!
today you will be a salmon returning to their home stream to spawn (lay eggs). The only problem is that you cant remember which way to go!
You seem to recall (remember) the distinct smell of Strawberry, orange, and then Vanilla almost in a pattern
it went:
Strawbery, Orange, Vanilla
Strawbery, Orange, Vanilla
and then finally Strawberry when you reach your home stream.

So, you begin to leave the ocean repeating the pattern in your head as you swim "Strawberry, Orange, Vanilla..."

#7 You have almost made it home when you notice the water is very murky. It becomes very difficult to see and even breathe with all of the silt in your gills and eyes. This is the home stretch it is almost time to spawn and you need that cold, clean, clear water. Which way do you go?

A- Left

2

B- Straight through the Murky water

If you are here right now with a score of 100%, you have made it to your home stream to spawn and continue the Salmon life cycle!!
It wasn't easy, but you never gave up! :)

***If you did not get 100%, don't stress!***
you may have spawned somewhere less desirable, or you didn't survive. It is all a natural part of the salmon life cycle!

Congratulations!
