Barney themed children's birthday

There are several here that are having a Barney themed birthday for their 1, 2 and 3 year old children and are desperate to get a Barney costume for the event so that Barney can make an appearance. There are some remotely similar looking suits available, but they are rare and difficult to get. Somebody asked me to wear one of those at the end of October. It will be really hot in that suit around that time of the year here in the southern hemisphere.
