Kensli Davis of Milledgeville said her mother ordered the cake from Dairy Queen and asked for the decoration to be inspired by Moana, the 25-year-old's favourite Disney cartoon.
"The manager stood behind me while I pulled the images off the Internet", Walker said to USA Today.
Either mom didn't speak clearly or the person taking the order didn't listen carefully, because what Davis got had nothing to do with "Moana".
"Our cake decorator designed a cake based on what she thought she heard the customer order".
Walker says she was terminated on Monday, which also happened to be her birthday, after working at that Dairy Queen location for about a year.
"It's not amusing to me", Walker said in a phone interview with USA Today. "This is back-to-school time".
"I guess when they said that I love cartoons, they were like, 'Let's throw a little pony on there.' So they put a little pony on there. It's not amusing to me".
A misunderstanding at a Dairy Queen led to a request for a Moana-themed ice cream birthday cake getting turned into a marijuana theme.
"I think they thought that she said "marijuana" because we are from south Georgia and kind of have an accent".
I haven't had a chance to tell y'all about our experience this weekend with my birthday cake. "The customer said it was fine, paid for the cake and left", one of the Dairy Queen owners Al Autry said to USA Today.
She says the first one was so good - and hilarious - she didn't take them up on it.
The person who made this cake must have been high. Davis told CBS affiliate WMAZ. "The whole family thought it was the funniest thing ever and said it would definitely [be] a birthday to remember".
