SpongeBob Tower Defense Dragon Units: Dunces & Dragons Guide

The confirmed SpongeBob Tower Defense dragon-event units are Squidly Tentacles and Planktonamor. They were listed as part of the limited-time Dunces & Dragons Event, which also introduced the Middle Ages raid, Dragon Scales, Dragon Capsules, and a new world. However, the available event record says that eight units were introduced while naming only these two, so a complete list of all dragon units cannot be confirmed from the current source.

Confirmed dragon units

The event page identifies these units under its unit section:

• Squidly Tentacles
• Planktonamor

The source does not provide their rarity, damage, range, attack type, upgrade path, placement cost, or combat abilities. It also does not identify whether either unit was stronger than the other. As a result, there is not enough verified information to create a reliable tier list or recommend one unit over the other.

The event record describes the wider update as introducing eight new units, but only two names appear in the available unit list. That difference is important: the two named units are confirmed as event units, while six additional names and their individual details remain unconfirmed in the supplied material. It would be inaccurate to fill the gap with names from unrelated lists or to assume that every unit connected with the event had a dragon theme.

How the dragon event worked

The Dunces & Dragons Event ran from May 9, 2025, through May 19, 2025. Its event currency was Dragon Scales, which players could earn by completing the Middle Ages raid. The source does not state the raid’s wave count, difficulty, recommended units, boss mechanics, or Dragon Scale payout, so those details should not be treated as confirmed.

Dragon Scales were used to purchase Dragon Capsules. Each capsule cost 250 Dragon Scales or 249 Robux, according to the event page. The source does not explain the capsule’s exact contents, its odds, whether it directly granted one of the named units, or whether the two payment options offered identical rewards.

A simple evidence-based progression summary is:

1. Enter the Middle Ages raid during the event period.
2. Complete the raid to earn Dragon Scales.
3. Spend 250 Dragon Scales on a Dragon Capsule, or use the listed 249 Robux option.
4. Check the capsule’s reward to determine whether it contains an event unit.

The source does not confirm whether Dragon Capsules were available after the event ended. It also does not confirm whether the units could later be obtained through another banner, shop rotation, trading system, or rerun.

Event availability

The event article is marked as content that has been completely removed from SpongeBob Tower Defense, although no removal date is specified. Since the event’s listed end date was May 19, 2025, the available evidence supports treating it as a past limited-time event rather than a currently active activity.

That status means players should avoid assuming that Dragon Scales, the Middle Ages raid, or Dragon Capsules are still obtainable. The supplied material does not document a rerun or a permanent replacement method for either Squidly Tentacles or Planktonamor.

The event was based on the SpongeBob SquarePants episode “Dunces & Dragons.” This explains the medieval and dragon theme, but it does not provide additional unit statistics or acquisition details.

What remains unknown

The current source confirms the event names and broad currency loop, but it does not establish:

• The complete list of eight introduced units
• The rarity of Squidly Tentacles or Planktonamor
• Their abilities, stats, upgrade costs, or recommended placement
• Dragon Capsule drop rates
• Whether either unit was guaranteed from a particular number of capsules
• Whether the Middle Ages raid had exclusive rewards besides Dragon Scales
• Whether the event or its units returned after May 19, 2025

For the currently documented facts, see the Dunces & Dragons Event page. It is the available reference for the event’s dates, named units, Dragon Scale currency, raid requirement, and capsule pricing.
