Characters Present


Grandpa gets out of doing chores by faking a "bad bug", though the Rugrats think he actually ate one. To take care of this, they find some "good bugs" for Grandpa to eat while he sleeps! - Description from Klasky Csupo



Grandpa Lou claimed that he used to stay up for fifteen days in a row and liked it. However, one hard-to-beat record for the most time without sleep is 264 hours, or eleven days, which was an extreme. After about a week, a person would hallucinate due to the lack of REM sleep. After less than two weeks, a person would experience brain damage, possibly permanent. It's pretty impossible for him to do this, much less enjoy it. It is possible that he is exaggerating with the number 15.


  • When Stu and Didi are in the garden, Didi is wearing a purple sweater but when she is zoomed in on and says" They're so Sweet" her outfit is the same red dress she always wears.

At the end of one scene, the babies are in their regular clothes instead of their pajamas.

  • Grandpa lies that he is sick with a bug, and the babies take it literally and think he is sick because he ate a bug. Phil and Lil eat bugs a lot without getting sick, so Tommy concludes it must be a bad bug.
  • Grandpa says he was once ensign in the corps, although other episodes show him in the army
