One day we learned about fish... sure its a little silly but I only used words that start with the letter F!!

Pre Cambrian

Fish
Frozen feeding faeries
Feeding faeries for funny faces
Funny faces fake follies finding fops
Fops flirt fluidly
Fluid feels fiery forming flames facing Firenze
Firenze faces floating fish
Fish feeling friendship
Friendship feeding folks
Folks feeding fish
