Ep. 2: Shin juega con un triciclo, tiene problemas estomacales y se une a su padre en un restaurante.

2

After much hesitation, Misae gives Shin a tricycle to play with. When he accidentally drops it into a dirty lake, Misae tries to find it. While this is happening, Shin runs off, making Misae think that she's been a bad parent, but it is revealed that Shin ran off because "Action Mask" was starting. Shin-chan has an upset stomach as he has not gone to the toilet for three days. The teachers give him medicine and he gets well. Shin-chan goes to a restaurant with Hiroshi as Misae is not home, but Hiroshi finds it tedious being with Shin-chan and is relieved when Misae returns. (Source: Wikipedia)
