Once again, there is no O in the Motif Index (probably because it looks too much like a zero). So I just searched for random terms that begin with O in the Motif Index, and came up with this gem:
J1852.1.2 Oil sold to iguana
This is a folktale from the Shan people in Southeast Asia, titled The Poor Man.
The tale tells about a poor man who wants to make some money. He hears about a city where there is a shortage of oil, so he borrows money from his friends, buys two gourds of oil, and sets out to sell it. On the way to the city he sees an iguana; the iguana sees him too and runs. The man chases the iguana, hoping to catch it for dinner, but the lizard disappears in a hole in the ground. The man starts digging - and lo and behold, finds three pots full of gold, and three pots full of silver. He tosses the gourds of oil away, takes the six pots, and sets out to the city.
When he gets to the marketplace, he wants to walk around, but the pots are very heavy. He goes to a house, and asks the people who live there to watch his pots, saying "there is only a little oil in them." He spends the day strolling around the market, enjoying the thought of being rich... and by the evening, he completely forgets which house he left the pots in. So he goes from door to door, asking for his pots of oil, but everyone denies having them.
Disappointed and tired, the poor man goes back to the hole of the iguana, hoping to find more gold. What he does find, however, is a day's wages in coin, and a written note: "The owner of the gold and silver thanks you for carrying his pots to the city."
The poor man goes home and remains poor.

I have so many questions. Who was the owner of the pots? Was it the guy the poor men left the pots with? Was it someone else? Was it the iguana?!?!
