Differences from the story
- Nicholas's real baby sister's name is Grace and not Hannah. The real baby is named Chloe, instead of Grace in the story.
- There is no mark of evil on the baby in the episode. Thus, Nicholas is not worried about the baby until she starts acting strange.
- The episode adds a female friend character.
- Tyrone Savage (Nicholas) played Daniel in season one's, "It Came from Beneath the Sink".
- Booth Savage and Janet-Laine Green, who played Nicholas' parents, not only were a real-life couple at that time, but they were the real-life parents of Tyrone Savage, who played their son.
- It is shown that Grace's real parents are monsters as only their hands can be seen when they are reunited with her.
- The toy block that Sam picks up from Grace's crib bears the Goosebumps "G" logo.
- When Nicholas is fighting with the baby for the remote, the channel is switched and a scene from a previous episode, "Say Cheese and Die" is shown. Ironically, the next episode after Strained Peas was its sequel, "Say Cheese and Die - Again!"
- This is the lowest rated Goosebumps episode on IMDb, with a score of 3.7/10.
- In one scene, Sam leaves Nicholas's house with a skateboard with the cover design of The Haunted Mask. The skateboard is the same prop as seen in Grady's room from The Werewolf of Fever Swamp episode.
