Pip and Pop are two inseparable purple otters who live on the otter pond behind the Big Blue House on Bear in the Big Blue House. They are cousins, and share a set of grandparents: Otto and Etta Otter. They are both obsessed with clams (though Pip loves steamed clams, whereas Pop loves stuffed clams), and enjoy the game of checkers. They often speak simultaneously — saying or singing the same thing in unison. They look almost identical, but there are a couple of minor differences. Pop's ears are slightly higher on his head, and his eyes are slightly larger and closer together than Pip's. Thus, "Pop's ears are on top" and Pip's ears are towards the front. Another difference Pip and Pop have noted about themselves is that Pop is able to make some very funny faces that Pip isn't able to. According to Noel MacNeal, "Pip was always on camera left. So ... it's Peter Linz on the left, and Tyler Bunch on the right."[1] When Pip and Pop aren't at the Big Blue House, they can often be found at the Otter Pond. This is no surprise, as they love water. They can also be found hanging out and playing in the bathtub a fair amount. One of Pip and Pop's favorite toys is a talking clam named Clammy, which they receive in the mail in "The Way I Feel Today." They were both brown and performed by Joey Mazzarino and David Rudman in the pitch tape for the series.[2][3] In the pitch tape, Pip was named "Pummel", which was changed presumably due to sounding too violent ("pummel" is synonymous with the term "beat up").
