Are there any more comics in Super Pochaco Whopping Topping Book (like the two scans you posted a while back), or are you aware of any other media with similar comics featuring those characters? Thanks for any help!
Those are the only two comics featured in Whopping Topping Book! Pochaco has a couple of comics featured in 10th Anniversary book that were posted online previously. There is nothing else with Taruco however.
I'll link the danbooru mirrors of the comics here. Very few are translated.
Pochaco & Jamane/Minamida (her manager) - Pochaco acquires her headphones.
Pochaco & Jamane - Jamanes mask resembles a famous noodle brands packaging...
Pochaco - Pochaco receives feedback from her fans (translated)
Pochaco & Jamane - Snacking
And her April Fools comic, a parody of Kodoku no Gourmet. 1, 2, 3
