That's strange, the images show up totally fine for me. They seem to be hosted on archive.shikadi.net. Maybe you have that domain blocked?
Good catches, Grandy02! That Cosmo one is very hilarious!
Anyway, I found a few references:
I once saw a bag of dog food with an expiration date of March 14! Maybe that's the kind of dog food Mortimer gives to his dog!
In Donkey Kong 64, the level Fungi Forest has tomato enemies that look just like the Tomatooths from Keen Dreams! They even hop after you! The only difference is that they are much bigger and have blue eyes.
In Pikmin 2, the enemy Pileated Snagret looks very similar to an enemy from Cosmo. Both have very similar methods of movement -- hopping!
