Etzer may have taken the prompt 'Cosmic Dolphin' too literally in the construction of "Cosmic Dolphin". It's a level that certainly integrates elements of the cosmos such as shimmering stars, but at the same time, it also features detailed depictions of dolphins (detailed for 1.9 at the very least). It's a cute level and I remember that it used to lag my old iPad 4 a lot (seriously, the only reason why this level probably wasn't featured was because of its excessive object count and lag). Aside from the impressive dolphin art and stars, it probably doesn't stand out too much from its contemporaries. However, it's a solid level for what it is and it reminds me of a time when easy 2* levels actually had gameplay (shocking, I know?).
