Vintage 90's 1990 1991 Buddy Corp. Pony Set of 2 unicorn Pegasus ponies

Vintage 90's 1990 1991 Buddy Corp. Pony set of 2. Comes with a white and pink hair unicorn Pegasus! She has a blue saddle and used to flap her wings and light up. Also comes with a purple pony with blue and purple hair. Yellow saddle. Used to light up and make gallop noises I believe. I loved these as a kid lol. There is scews underneath so maybe can get them to work? Maybe they have watch batteries? I'm not sure. Also the hair is a bit frizzy but overall great vintage condition. Happy to answer any questions ♡♡
