Actually, the Walrus show is more boring than the sea lion show. The best and easiest way I've found to build up your shows is to train each animal up to three or four dots in each trick, then let a trainer get them the rest of the way. Check back once they've trained them all the way on a trick to do the next batch. Also, make sure to have plenty of time between shows and on occasion lock your trainers up in a small walled off area to make sure your animals get some time to themselves.
