I dreamed of Birdgirl having cartoon SFX. I would share the cartoon SFX used in my recreations of this show. The cartoon SFX are coming from the cartoon named Baltimo. Baltimo would be played on a TV screen or a computer. Here are some examples of these SFX used in the Baltimo cartoon (Listed by episode, not all included):

Sound Ideas, SWISH, CARTOON - TWIRLING SWISH, MEDIUM (Heard once in "We Have the Internet".)

Sound Ideas, ZIP, CARTOON - QUICK WHISTLE ZIP OUT (Heard once in "Thirdgirl".)

Sound Ideas, PLINK, CARTOON - SOUR PLINK (Heard once in "We Have the Internet".)

Sound Ideas, HOP, CARTOON - SINGLE JEWS HARP HOP 01 (Heard once in "We Have the Internet".)

Sound Ideas, BOINK, CARTOON - BOINK 01 (Heard once in "Baltimo".)

There are also original cartoon SFX made for the Baltimo cartoon. Here are some of them:

A slide whistle whirling up (Heard once in "Thirdgirl".)

A big metal clang (Heard once in "Pilot".)

The episode "Baltimo" has the Birdgirl and the team stuck inside the cartoon and the cartoon gets cancelled at the end.
