Nostalgia is a great way to market to the adult audience. The methods would be to advertise the product recalling the action of getting and keeping a pokemon. For example an advertisement for the Cat food can show meowth / pickachoo being taken into the ball by its owner. Then the question -- 'Meowth was kept in the pokemon ball, you used him in fights dint you? You can't nourish your cat in a ball now -- but give him best nourishment -- with Mcatball-meat ball for cats. For doggies we have to similarly bring up an association with throwing the ball -- 'do you throw sticks for your dogs to catch?' Does he regain energy? Remember that Pokemons need to be nourished.

Question 3

Recommend two (2) suitable Advertising and Promotions tools to complement the advertising campaign.

Pet shops continue to dominate distribution for pet care products in Singapore and they have captive consumers. (Euro Monitor, 2010) Thus all pet related services go through them. The strategy therefore is to offer some extra benefit to the pet superstores and dealers to promote the brands that bring in the nostalgia. This may take the form of a) free goodies for the customer in the form of pokemon related stickers...

Pokemon characters can also be sold as chewies instead of bone chewies and play things. Though pet food is the prime market giving away pokemon related memorabilia to be the play thing of pets, and also the things the master can use to play with the pets will certainly make those who know about the pokemon series want to buy it.
