The words "Pizza Time Theatre" were dropped from the logo and it simply became "Chuck E. Cheese's". The "Chuck E. Cheese's" typeface from this logo continued to be used on the red derby of the animatronic and walk around Chuck E. Cheese characters until the mid 90's.
The changes to the logo were a different font for "Chuck E. Cheese's" and the addition of the word "Pizza". Also the font extending all the way to the chain's current logo was introduced for the first time.
