The evolution of Dr. Bunsen Honeydew.
|Image||As seen in / Year||Notes|
| The Muppet Show|
|Dr. Bunsen Honeydew makes his debut in the Paul Williams episode of The Muppet Show.|
| The Muppet Christmas Carol|
|Bunsen's look changes slightly but steadily over the years. His face goes from a wider-than-tall look in the early 1990s to considerably thinner over time. His glasses are adjusted to match the contemporary setting for this appearance and his appearance in Muppet Treasure Island.|
| Muppets Tonight|
|The doctor receives a white lab coat, replacing the light blue coat he had been wearing since his debut. His standard red tie is further replaced with a black tie.|
| Muppets from Space|
|His wardrobe returns to his classic colors for Muppet Labs. His face reaches its thinnest design, and will remain this shape from 1999 until 2008.|
|Bunsen's looks have changed tremendously. Even though the design is turning to a more classic, rounder head shape, his accentuated chin and bigger ears, as well as their lifted position, provide him with a more cartoony look. This look is kept up through A Muppets Christmas: Letters to Santa.|
| || Muppet viral videos|
|A new Bunsen puppet appeared at the D23 Expo in September 2009, which again more closely resembles his vintage appearance on The Muppet Show. Further appearances on the Muppets' YouTube channels (with videos like Haunted Holidays and Bohemian Rhapsody) or the Give a Day. Get a Disney Day. promotional campaign have since used this likeness.|
