The Scales (Two characters) has debuted in two locations:
In the House's Kitchen, the first scale was used for balancing.
In the skidoo segment (Country Store), The second scale was used for weighing.
There was also a non-talking scale in the felt frame. The numbers 2 and 4 were on each side, and 4 was down because 2 < 4. Later, the numbers 0 and 9 come in and jump on the 2, causing it to go down because 0 + 9 + 2 = 11 and 11 > 4. The numbers became the second clue.
We also see the weight of several other characters in this episode:
Blue: 20 pounds (9.07185 kilograms)
Scale (Kitchen) with Mr. Salt, Mrs. Pepper, and Paprika: Three pounds (1.36078 kilograms)
Bell: Two pounds (0.907185 kilograms)
Altogether, their total weight is 163 pounds (73.9356 kilograms).
Steve alone weighed 138 pounds (62.5957 kilograms). As he said that his two green striped shirts he held on to do not fit him anymore, his weight is higher than it was when this episode was produced.
Surprisingly, there is no Kevin or Durate version for this episode.
Even though this episode aired in 1999, the closing logo shows the episode copyrighted as 1998 instead of 1999, revealing this was actually taped in late 1998.
After Steve placed all groceries on the shelf and just when Blue placed her pawprint on the screen, the two grocery bags disappear.
Popcorn should not be in the fridge.
A similar goof happens in the earlier episode Snack Time with grand crackers.
