Rugrats - Season 5 Episode 4 -

It seems like it when Grandpa accidentally shrinks Chuckie's clothes in the wash, after Chuckie got dirty. Afterwards, Angelica decides to play off Chuckie by thinking that he's a giant and that he'll squash Angelica, the Rugrats and the grown-ups. In the end, this action costs Cynthia her right to have cappuccino; her miniature cappuccino machine was brought over so Stu can fix it.
