There were various promotions that I will collect below.

 

 

Wai Wai Times vol 6 in 1987 there is a notice for a speed lottery for anyone who purchased products from this line. You could win a limited and exclusive 1987/1988 calendar which showed all the character birthdays. Tissues are also mentioned, which I assume were given for losing tickets.

 

Wai Wai Times vol 6 in 1987 contains a contest to become a character in this franchise. I believe these became the four human characters released later that year.

 

Wai Wai Times vol 6 in 1987 contains a notice where you can send in clothing designs on a postcard. I do not know if any of these were made into clothing.

 

 Wai Wai Times Vol 7 in 1987 contains the above contest for a chance to become a doll. I am not sure if this happened because I have not seen any dolls aside from the four who were already released at the time.

 

In a 1987 issue of Toy Journal I found a notice for “Letty Sensei’s Wedding Bouquet Present” campaign. I need a clearer scan of this to see what this was.
