What original animal mascot for Trix cereal was replaced by a rabbit in 1967?

Trix is a brand of breakfast cereal made by General Mills in Minneapolis, Minnesota, for the North American market and by Cereal Partners (using the Nestlé brand) elsewhere in the world. The cereal consists of fruit-flavored, sweetened, ground-corn pieces. They also make yogurt.

The original Trix mascot was a stick-figure flamingo.

When the cereal first debuted in 1955, General Mills designed a simple, accurate flamingo mascot. We would probably sneer at the thick lines and small eyes of the flamingo (or any mascot from that time, actually.

It would take five years before the Rabbit, originally a hand puppet, would grace the front of cereal boxes.

In 2015, General Mills announced it would no longer use artificial colors in its cereals, and that Trix would be among the first to change. Trix would go from six colors to four because satisfactory natural alternatives were found for orange, yellow, red, and purple but not blue or green.
