Himmel Mancheese is an orange, flying, jellyfish-like creature that can carry living things inside of it as a means of transportation.
Himmel Mancheese appears to be friends with Emotion Lord due to the fact that he was affectionately rubbing against him and also allowing the Emotion Lord to ride in him.
Himmel Mancheese seems to like Catbug because they were playing a game of tag and was giving Catbug a ride to see Wankershim. Catbug also referred to Himmel Mancheese as his friend. Also, he has soft tacos with him while the Emotion Lord didn't, though that was because he put on the Temporal Pair-o-Sox.
