Which of the four Teletubbies had a triangular antenna on its head?

Ah, TELETUBBIES. Love it or hate it, you probably have an opinion. The series was definitely designed for preschoolers, with its bright colors, repetition and gentle nature, and so many adults found it grating. And that was a shame if you had a toddler hooked on the cutely surreal world of these multi-colored creatures with television screens implanted in their abdomens.

The show premiered in the UK in 1996 and on PBS Kids a year later. It was very popular and originally ran for five seasons (new episodes were made a few years ago; PBS has yet to air them).

The four main characters differed in two major ways – they were each a different color and each had a differently shaped antenna atop its head. One antenna was basically a stick and pointed straight up. Another was curly, kind of like a pig's tail. Another was a circle. The last one was shaped like a triangle.

So which of the four Teletubbies had the triangular antenna on its head?

Think about it and I'll post the correct answer later.
