Thailand
From My Little Wiki
Only a handful of G1 ponies were made in Thailand. These ponies often varied from the same pony made in China or Hong Kong.
Moutain Boy Ponies
Thai Ice Crystal - differs from Hong Kong Ice Cyrstal by the dark green streak in his mane
Thailand Tornado - Only two examples of Thailand Tornado have been found so far. The blue streak in his mane falls on the opposite side to the Hong Kong version and he is made of a softer plastic.
Baby Fancy Pants Ponies
The Baby Fancy Pants Ponies released in Year Seven (1988-1989) were made in both Thailand and China. The ones made in Thailand were sold in the US and the ones made in China were sold in Europe. The ones distributed in Europe had different colored forelocks whereas the US ones had single color manes.
