Diddl

Diddl is a German comic book character created in 1990. He's a white jumping mouse, with extra large feet & ears. I'm unable to get a year for this figure, but no website on the box so I'm guessing 90s. He's listed as figure 37.
 

Skateboard Actyl

The Skateboard Actyl is a skateboarding dinosaur from the Daring Dinos Adventurers line released by Maeritus in 1993. I think the card back lays it all out pretty clearly:

Daring Dinos are mutant dinos that came to life when a mad scientist accidentally went back in time to the Jurassic Period and the monster period simultaneously when he pushed the wrong button on this time machine.

There you have it - pretty straight forward.

Mickey Mouse (XIV) & Minnie Mouse (II)

Mickey & Minnie return for a tandem pin. Online sources date this pin at 1975 from Germany. 

 

Amplifiers

Amplifiers was a toy line released by Jakks Pacific in 2018. The set featured skateboarders, scooterers, & bikers. All 3 could be launched with a rev up launcher that sets the large rear wheel in motion. Skateboarders came in numerous colorways and also in 2 different position (note the pink shirted figure is standing over the rear wheel rather than up on the nose). Some figures came with ramps and others in 2-packs.
